LabVIEW Control Design and Simulation Module version 2013

I have had Labview downloaded for quite some time now. Downloaded control design and simulation module. Installed it. When i go to use it in the
functions menu, only the window appears. Opening it shows an empty window. I have attached a screenshot of the issue. Could someone please explain to me what the problem is and how I can go about fixing it?

As Altenback said, It is very possible it expired or it needs activation. To see for sure, go to your "NI License Manager" and expand the Modules. you should see:
If not green then you have to fix the license.

Control design and simulation module

Hi,
I am new to Labview and i am trying to work on Control System design. I have downloaded and installed the Evaluation Module of Control Design and Simulation Module. The problem I am facing witht this is its not showing any control fuctions in functions Palette. While installing it said its installing only control design and simulation assistant. Please, can anyone help with this.
I am actually looking at this module to implement Sliding mode control for non linear systems. I would like to know if there are any examples to implement this??
Thank You.

Hello
The problem is the following. The version of LabVIEW that you are using does not match the version of the evaluation version of LabVIEW Control Design and Simulation Module (CD&SIM). If that happens, the installer will not select the support files for your LabVIEW. If you download LabVIEW 2011, then you must install CD&SIM 2011.
Now, the module in the current version does not have an example with sliding mode control. But using this module, you can easily implement the algorithms and simulation its result using the Control and Simulation Loop.
Hope this helps.

Control Design and Simulation and DAQ

I'm learning Control Design and Simulations. I have some questions about it.
1. For System Identification use, we can find the transfer function/model of the system by feeding data measurement from the system. But, how long data do we need to be sufficent for Identification System to estimate the model? Until the get saturated value (steady state)? or any other intervals? What if the system is unstable? How will Identification System Toolkit estimate that case?
2. For connecting to hardware, we just connect the clock in the simulation loop to the hardware? And the simulation loop will simulate the blocks inside once it got the trigger/data from the DAQ? what about the step time and solver? Do they follow the timing from hardware? or they will run on their own supplied values/clock?if we use USB DAQ, we can't have any clock from it (as far as I know it's because USB connection is not that stable for clocking since it might be any jitters or delays.) So, how do we configure the timing parameter for USB DAQ?
3. There is possibility to convert model in transfer function to state space, how do we know the states inside that conversion?
Any helps would be great...
Thanks in advance...

Dear Chin ho,
After going through your questions I found some documentation which will be useful for you. But I you still have more questions, you can reply me any time.
1- About the data and amount of it I couldn't find any info but maybe you can use the new functions in LV version 2009 and find your answer.
Estimating States of Nonlinear Stochastic State-Space Models with Extended Kalman Filters
In previous versions of the LabVIEW Control Design and Simulation Module, you can use the Discrete Kalman Filter function and the Continuous Kalman Filter function to estimate the states of a linear discrete or linear continuous stochastic state-space model, respectively. In the LabVIEW 2009 Control Design and Simulation Module, you can use the Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function to estimate the states of a nonlinear continuous or a nonlinear discrete stochastic state-space model, respectively.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function estimate model states of a partially observable plant based on noisy measurements. First, use the SIM Discrete Nonlinear Plant Model template VI or the SIM Continuous Nonlinear Plant Model template VI, located in the labview\templates\Control and Simulation directory, to define the system model. Then use the the Discrete Nonlinear Noisy Plant function or the Continuous Nonlinear Noisy Plant function to simulate the discrete or continuous nonlinear model, respectively, with the addition of noise. Finally, use the Continuous Extended Kalman Filter function or the Discrete Extended Kalman Filter function to estimate the states of your model.
The Continuous Extended Kalman Filter function and the Discrete Extended Kalman Filter function linearize the nonlinear system either by calculating a Jacobian matrix internally or by using an external Jacobian matrix that you define. Use the SIM Continuous Jacobians template VI or the SIM Discrete Jacobians template VI, located in the labview\templates\Control and Simulation directory, to define an external Jacobian matrix.
Refer to the LabVIEW Control Design User Manual, accessible by navigating to the labview\manuals directory and opening CD_User_Manual.pdf, for more information about estimating the states of nonlinear stochastic state-space models with extended Kalman filters.
2- I think that I found a pdf document about this part of your question which will be helpful. If you would like to give your email address, I can send it to you.
3- About this part you can check the help function in LabVIEW when you open the "CD Convert Transfer function To State-space" function in your front panel.
I pasted some info about the mathematic part below.
The LabVIEW Control Design and Simulation Module provides tools to study the dynamics of systems described by linear time-invariant (LTI) continuous and discrete models. You can create deterministic state-space, transfer function, and zero-pole-gain models. You also can create stochastic state-space models and the second-order statistics noise models. You can use these forms to describe both single-input single-output (SISO) and multiple-input multiple-output (MIMO) systems.
Continuous transfer function and zero-pole-gain models use the s variable to define time, whereas discrete transfer function and zero-pole-gain models use the z variable to define time. Continuous state-space models use the t variable to define time, whereas discrete state-space models use the k variable to define time.
Deterministic State-Space Model
Continuous
x(t) = Ax("t) + Bu(t)
y(t) = Cx(t) + Du(t)
Discrete
x(k + 1) = Ax(k) + Bu(k)
y(k) = Cx(k) + Du(k)
Stochastic State-Space Model
Continuous
x(t) = Ax(t) + Bu(t) + Gw(t)
y(t) = Cx(t) + Du(t) + Hw(t) + v(t)
Discrete
x(k + 1) = Ax(k) + Bu(k) + Gw(k)
y(k) = Cx(k) + Du(k) + Hw(k) + v(k)
Second-Order Statistics Noise Model
Q = E{w . wT} – E{w} . ET{w}
R = E{v . vT} – E{v} . ET{v}
N = E{w . vT} – E{w} . ET{v}
where
t is continuous time.
k is the model sampling time multiplied by the discrete time step, where the discrete time step equals 0, 1, 2, …
x is the model state vector.
u is the model input vector.
y is the model output vector.
w is the process noise vector.
v is the measurement noise vector.
A is an n × n state matrix of the given model.
B is an n × m input matrix of the given model.
C is an r × n output matrix of the given model.
D is an r × m direct transmission matrix of the given model.
n is the number of model states.
m is the number of model inputs.
r is the number of model outputs.
G is a matrix relating w to the model states.
H is a matrix relating w to the model outputs.
Q is the auto-covariance matrix of w.
R is the auto-covariance matrix of v.
N is the cross-covariance matrix between w and v.

Control, design and simulation

Hello everybody,
I am trying to run a simulation in Control Design and Simulation module. My simulation consists of various simulation systems. The subsystems are working as desired when run as separate units, but when I run the complete system, the subsystems fail to produce the output values.
I have not used any local variables or any discrete function vi inside a subsystem.
Where am I wrong ? Any help would be much appreciated.

I mean the indicators connected to various subsystems are inactive and don't produce any output values. I tried to find the error using the Error Cluster, but it didn't show any error. I am using LabVIEW 2011. I have attached the complete system including the subsystems. The individual systems are working fine. I changed the solver too, but the problem persisted. Please try to identify the error.
Barp wrote:
When you say: Fail to produce a output, what do you mean?
On the right side of the Control and Simulation loop you have the 'Error Out' cluster. Create a control from it and see if you have an error. Also, which version of LabVIEW are you using?
If this is not producing an error, then try to change the solver you are using. It would help if you could post your code (or at least pictures) of it.

Control design and simulation palette

Hi all
I've recently installed LV 8.2 professional edition on my PC.
Watching the function palette i've seen the sub-palette 'Control design and simulation' empty... Is it normal? Do i need some toolkit to see something in it?

If LabVIEW is installed in "c:\program files", it means that you installed LabVIEW 64bit. You should install LabVIEW 32bit, which will go to "c:\program files(x86)" and will be compatible with your toolkit.
There is nothing wrong with the installer. You simply picked the wrong product.
Do NOT copy files between the two mentioned folders. One is for 32bit applications and one is for 64bit applications (assuming you have a 64bit OS).
The toolkit is not compatible with 64bit LabVIEW (Details).

Control Design and Simulation Tutorial

Hi
I'm starting off with a coursework which requires use of the Control Design and Simulation functions. Before I ask any silly questions i'd like to see the hand on tutorial, it's referenced in this white paper.

However the ftp link to the tutorial doesn't work, does anyone else have an alternative link, or could supply the tutorial directly.
I appreciate any assistance.

How to reset indicators in a control design and simulation loop before each run?

Hi,
I am new to Labview. I have tried using property node to reset indicators before each run. But since it is in a simulation loop, it gets resetted many times. I am primarily interested in resetting only before each run.
Any hint will be of great help.
Thank you!
Regards,
Divya

Hi Divya,
This KnowledgeBase article describes 2 methods for resetting your Front Panel programmatically:
http://digital.ni.com/public.nsf/allkb/08E7DDAE66A7D02C86256DDA00630E75
However if you have tried these methods, and are still not getting the behaviour you want, it would be easier to help if you could post your code (or even a screen shot of the section of code where you're trying to reset your values)

Can't install Control and Simulation Module in LABVIEW2009

HI all,
I m using LABVIEW2009 x64 and wanted to update control module in it.
when ever I try to install the Control DEsign and Simulation module, the setup won't proceed.
IT shows the following error message :
NI LabVIEW 2009 Control Design and Simulation Module
The Control Design and Simulation Module requires LabVIEW 2009 Full or Professional Development System to be installed.
however, I have already installed and reinstalled once as well. Please help me.

Hi Rishabh,
Unfortunately, we do not have a version of Control Design and Simulation for x64. You can try to install the 32-bit version of LabVIEW instead on a 64-bit OS. This should allow you to install CD&SIM.
Please let me know if can help any further.

Fpga, Control and Simulation Module

Hello,
I am trying to implement control by Control and Simulation Module through NI CRIO 9024. The error message pops up when trying the run the RT vi.
Other vis which are not coded by the Control and Simulation Module can work properly. However, when it comes to the Control and Simulation Module, the error message pops up. Is there anything wrong with the installation of the Control and Simulation Module? Please let me know if you have an idea about that. I appreciate your help.

Hi Richard629,
As seen in this Knowledgebase article, you most likely do not have the Control Design and Simulation module installed on the controller. You can use NI Measurement & Automation Explorer to install the Control Design and Simulation module on your controller.

100% CPU using LabView 7.1 and DSC module

Seven years ago I used BridgeView and PXI to execute a project, and the results were so good that after that initial system, I installed one more using BridgeView, and three more using LabView 7.1.
BridgeView is working very well, but lately, LabView 7.1 is giving me more and more problems. It all started in a system running LabView 7.1 and DSC on Windows XP, using a PXI-8187 controller with a PXI-1042 chassis. I have two PXI-6533 digital I/O boards, one PXI-6030E multifunction, one PXI-6713 analog output board, one PXI-6602 counter board and one PXI-8422 serial com. board. In may/06, all of the sudden, the CPU went to a 100% use. Since I am running PID's to control a flash-butt welding machine in a steel factory, this was extremely dangerous. I changed the controller and everything went back to normal. It was running fine until december/06, when the same behavior appeared again. This time changing the controller did not help. We increased the system memory, from 256 MB to 512 MB and everything worked fine. But one month later (january/07) the fault reappeared. This time we changed the chassis and from that moment to this time, we are running smoothly.
Application problems were suspect from the very first time this problem appeared, but I was unable to identify the source, if any. I used PROFILE VI's and apparently the write/read tags were taking all the processor resources. However, changing the routines and disabling communications, and optimizing CPU intensive programs never solved the CPU overload.
Until now, I was aware of only one system showing this erratic behavior. But today I went to check another system, with a totally different application. This one is used to measure the thickness of the steel sheet on a rolling mill. Is not so resource-intensive, but the maintenance folks told me that every time they turned off this particular system, they always had problems trying to turn it on.
I was suspecting of a PLC-communication related issue, but what I found turned my alarms on. I turned off the system, which was fully functional, and turned it back on, and there it was, CPU load at 100%!. Is exactly the same problem that I have on the welder. This system has a PXI-8184, a PXI-1042 chassis, Windows XP, one PXI-6030E, one PXI-6713 and one PXI-6533. I battled for 20 minutes to put the system back in normal conditions.
I specified every single board, installed everything and programmed all the applications. The BridgeView applications have never showed anything like this. I am using the DSC (Datalogging and Supervisory Control Module) on both applications, and the Lookout Protocol Drivers are communicating to Modicon PLC's.
Please, I need help to solve this issue. I believe none of your actual Knowledge Base "100% CPU" articles apply to my case...
Thanks in advance...
Antonio Jimenez
[email protected]

Thanks for your reply...
Yes, sometimes I have the feeling that the systems works again because some file or database gets initialized after so many reboots.
Intentionally I turned off all the events and alarm logging to disk. Also the historical data logging is disabled. This is done by code, every time the main VI is started. This was included precisely to save CPU processing power. However, I am communicating to PLC's, and of course I have to declare variables inside the citadel database to make the communication possible.
Right now I can't have access to the application, because the mill is rolling, but during the next maintenance stop I will check the database location and size, and I could change the directory location the next time the fault comes up.

LabVIEW Control Design can't multiply an improper TF with a proper TF

I'm calculating a dynamic inversion where I need to multiply two transfer functions,
H = inv(G1)*G2.
All transfer functions G1 G2 and H are proper. However, inv(G1) is improper. Even though the resulting H is proper LabVIEW's Control Design tool fails to perform the multiplication complaining that one of the systems is improper. Works fine in Matlab.

Sorry, I forgot to add that I'm not using DAQmx, but doing it manually. I'm a beginner at this and am really stuck.
I've attached my basic file to the post so you can have a little look, and a screenshot as you may not be able to open some parts of the file due to my non-popular DAQ board. Please note that the DA value is not required, as I'm using the control ouput instead of this, and that the chart has now been modified to show error vs controlk output.
If I could get some help, I'd be extremely grateful.

Adding Proportional control using NI LabView Control Design Toolkit

I was just wondering is it possible to add a proportional control to your program using the NI Control design toolkit? There is a PID control fuction available, but i just want the P
Thanks

LC87,
A proprotional controller is equivalent to a multiply, so you could just create a transfer function with Numerator=[Kp] and Denominator=[1]. You could also use the CD Create PID Model (Parallel) with zero wired to the Integral Gain (Ki) and Derivative Gain (Kd). If you are going to implement this in a Simulation Loop, then all you need to do is use a multiply primitive.
