Control Design and Simulation palette doesn't appear

I'm using LabVIEW 2009 in Professional License. I've installed Control Design and Simulation Module with its all other required Toolkits. The problem is that Control Design and Simulation palette doesn't appear in the Functions Palette in any VI. Please help me with that.

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?
King regards

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 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 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.
http://www.ni.com/white-paper/5855/en/
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.

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

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 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.

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)

No icon in the control and simulation palette, toolkit is instaled

only question marks on the palette

Hi Adj;
Do you have more information on the LabVIEW and the control design and simulation toolkit you are using?
Here is a document that solves that issue for LabVIEW 8.2 and Control Design and Simulation Toolkit 2.1.1:

Imaq usb palet doesn't appear

Hi all,
Are anybody maybe encounter with problem after installation of imaq usb driver, the usb imaq palet doesn't appear :-(
Outside the Labview I succeed to connect by Vision Assistant but in VI Vision Assistant doesn't see usb camera.
Thank you in advance fore help.
Yan

Hi Yan,
This happened to me also. I have two versions of LabView, 8.5.1 activated and 8.6 Evaluation. I installed the driver like three times but I only tried with LabView 8.6 and no palet appeared. Finally, i tried in 8.5.1 activated and it was fine and working properly. If you have more than one version of LabView, my advice is to check them all and see in which one the palet is visible. Other than that, i can't really think of anything else.
Hope this helps,
Sabin

Can you do setup an unread mail folder that shows all unread mail regardless of what folder it really is in on the iPhone mail program somehow?
No.

This is not the iPhoto forum. In any case in iPhoto>Preferences select Mail or whatever email program you are using to email as the desired choice. You are probably sending directly through iPhoto.
