PID and fuzzy logic toolkit

He
I'm trying to create a motor position control using the PID toolkit. Is there a step response feature or another function that shows the response of the PID system, percent overshoot, settling time, etc? If not, is there a way I can create a step response using this toolkit?
thanks,
kirby

What is your setup so far?
If you are using the LabVIEW PID function and are controlling a plant, you could just change your setpoint and monitor the process variable on a LabVIEW chart.
If you are simulating it all, then there are step reponse functions that you can drop into your simulation loop like done here.

  • PID and Fuzzy Logic Toolkit for students

    As the thread title states.  I am a student running on the student version of labview.  I have a project I am working on that would greatly be benifitted by the PID and Fuzzy Logic Toolkit. Is there a way for students to get this without the $1000 price tag?

  • Fuzzy Logic Toolkit

    I followed the truck maneuvering example in the 'PID Control Toolset User Manual' and tried to use the 'I/O-Characteristic' test facility. But, when I tried to run the test facility, I realized that there is no run & stop buttons in the window. By the way I did not do the exact the same things the book showed. For instance, the example uses 5 terms for one input and 7 for another one. I used 3 for both. But, I think basically I followed the most steps he mentions in the example. Do you have any idea what went wrong, or can you tell me how I can run the test facility?

    Dear AdamB,
    I am just wondering if you could help me a bit. I have two problems. The first one is, I'm working with the fuzzy logic toolbox from matlab. I created a .fis file with some rules from the fuzzy editor in the fuzzy logic toolbox from matlab, wich I want to run in labview, with the matlab script. How can load the fis file? I tried with the examples attached, but it didn't work.
    The second problem is I have been doing some work with fuzzy logic toolbox in Matlab. The fuzzy inference system (FIS) built in Matlab environment is quite simple and straightforward. An example of the FIS in Matlab can be found in the attachment. Now I want to use the fuzzy logic toolkit from Labview to perform the same task. An example of the FIS in Labview can also be found attached. Although the FIS properties in Labview has been made the same as in Matlab, the result of the defuzzification is different. The FIS properties in Matlab are:
    And method: prod
    Or method: max
    Implication: Prod
    Aggregation: Sum
    Defuzzification: Centroid
    The FIS properties in Labview has been made:
    Defuzzification Method: Center of Gravitiy (which is another name for Centroid)
    If no rule is active: Take last value
    Inference Method: Max-Min
    Select form of rulebase: Normal rulebase
    For instance, if the input to FIS is Matlab is -3.51, the output is 0.202. However, with the same input, the output from FIS in Labview is 0.30.
    Perhaps you could help me?

  • Is to possible to control a motor by using fuzzy logic toolbox in Labview and motor interfaced with PIC microcontroller

    sir
     I am doing a  PG project on fuzy logic control of robotic arm,In this first i need to write a code in LABVIEW fuzzy toolbox and interface that that code with PIC where motor is connected and a tachogenerator should be connected to motor to send speed to LABVIEW through PIC microcontroller where ADC is inbuilt in it.
    Please help sir me whether  it is possible to do that ,if not tell me do i require any interfacing device  ,I am very new to labview 

    Now for this problem, Fuzzy can be easily used to control the plant. Here is the softwares that would help in this task:
    - LabVIEW Full Development System (FDS) 2009 or later - The is the LV version that allow you accessing the latest Fuzzy Logic develoment
    - LabVIEW PID and Fuzzy Logic Toolkit 2009 - This has PID and Fuzzy Logic functions available for you to develop your controller
    - LabVIEW Control Design and Simulation Module 2009 - This is a complete set of functions that allow you to simulate and develop advanced control applications. In your case, you probably will be using this module for simulation of the DC motor.
    Now, you also will need a way to read the encoder and control the voltage applied to the motor. You have several options from NI for that process. Probably a multi-function Board could help since they have digital counters and Analog Output signals. However, I can't recommend what would be best for this application, but the ideal platform is the CompactRIO platform for your application. They have a Real-Time controller and integrated Input/Output modules with signal conditioning that could allow you to directly drive the DC motor. I would advice to go to our webside (http://www.ni.com/compactrio/) and verify what this platform does. For this platform, you will also need the following sofrware:
    - LabVIEW Real-Time Module 2009 - Allow you to develop you application in Real-Time for deployment.
    Hope this helps.

  • Problem with Fuzzy Logic Controller Design window

    Hi,
    I'm designing a fuzzy inference system using the Fuzzy Logic Controller Design tool.
    But when I use up to 4 input variables, the Rule Editor window is out of center and I cannot see the left parts of the antecedents.
    See the attached picture.
    The visualization is not movable and resizing the window with system utilities does not give any results.
    Anyody can help me? Thanks!

  • Fuzzy logic controller for DC motor

    Hello guys!
    Can anyone help me out in giving inputs to fuzzy controller which has two input member function Error and Change in error. Is there any tool which can store the previous error and compare it with present error which gives the chane in error?

    Hello,
    Please look at the shipping example of Fuzzy Logic Toolkit in:
    C:\Program Files\National Instruments\LabVIEW 2010\examples\control\fuzzy\Tanks with PI control\FuzzyEx Tanks with PI control.vi
    This code will allow you to see how you can implement the error and rate error by using pure LabVIEW code. Now, if you have the Control Design and Simulation Module, this tool have functions that easily calculate the error and derivative for you.
    Hope this helps
    PS: Notice that this example is in LabVIEW 2010. The same example can be found also in 2009 by changing the number of the LabVIEW version on the path to 2009. Previous versions have this code, but they are a bit more difficult to understand. If you have previous version of LV 2009, I strongly recommend you to update to at least 2009 since on this version the toolkit was completely refactored. If you can't here is the location of the example previous to 2009:

  • Fuzzy Logic 4 hangs up

    Hi all.
    Mainbord: MS-6585F1
    Chipset: SIS 648 Max
    DDRAM: Crucial DDR266, CL 2,5
    AMIBIOS 1.1
    Intel P4 2.4 GHz
    Windows XP SP-1
    I have downloaded and installed MSI FuzzyLogic 4. As soon is i make some changes with this tool my computer hangs up. Nothing happens. After e.g. 10 Minutes I reboot manually and nothing has changed? Voltag is only for CPU available but not for DDRAM and others.
    With which Mainbords and Chipsets and BIOS is this tool compatible?
    Shoud I previously configure something in the BIOS make this tool work correct?
    Why does my computer hang up?
    Is there a documentation available?
    Thank you for your answers.
    Best regards

  • Difference in temp pc alert / fuzzy logic

    I use pc alert 4.0.0.9 and fuzzy logic 4.1.4.9 with a k7t266 Pro mainbord. When comparing the CPU temp. fuzzy logic always shows a temp wich is always 5 degrees higher compared to the temp pc alert shows. Which one is to be trusted ?

    Ok, the difference between the bios temp and the PC Alert temp (5 degrees) could be explained by running windows when checking with PC Alert; so nothing to be afraid of.
    But now I've a question about speedfan; I downloaded/installed the programm as some of you suggested but wonder if it runs as it should..
    The temp values which are showed are confusing...
    two of them are NEGATIV !-->
    temp 1 winbond W83627HF 43 degrees
    temp 2 idem 46 degrees
    temp 3 idem -47  degrees
    temp LM75 -47 degrees
    temp LM75 46 degrees
    Also I wonder how to discover which temp value is the cpu; I believe the temp1 winbond is the chassis (it's the same value as the chassis temp in PC Alert 3) ? The speedfan faq/help only shows how to rename the values but not which one is which...  (cpu temp according to PC Alert 3 is 50 degrees)

  • Problem using PID toolkit and control design toolkit to design the closed loop system. (for DC motor closed loop)

    Hi, i have facing some problem during i upgrade a project. This project is an opened loop system, it only achieved up to controlling the speed of motor, detecting the speed of motor, and switching the direction of motor while controlling the motor (This motor is a 12 VDC motor).
    In order to improve the project, closed-loop dc motor control system will be implemented to correct the error of the motor's speed and maintaining the speed for the initial setting. I would like to use PID control method to do the closed loop system.
    I already installed the PID toolkit V8.2 and control design toolkit V2.1.2, and i'm using DAQ usb 6221, LabVIEW 8.5

  • I searched and searched (fuzzy logic 4)

    Hello!
    Right now i was reading for over an hour and i cannot find the right answer about fuzzy logic 4
    I used live update to get the most recent drivers for my mobo msi 845 pe max2.
    (just to be complete I have the HT option in the bios while having a P4 2.4Ghz, for those who want to know, bios 1.20).....
    My problem:
    I used the "auto" function in fuzzy-logic and waited 3 minutes, the FSB is boosted to 164. Than the system hangs and restarts. (thats normal right?) the cpu-temp is 64C when it hangs..
    then after the reboot, nothing has changed and the fsb is back to 133???
    What is wrong? how can i overclock my system with fuzzy logic??
    Sander

    I would NOT use Core-Center Either with your Board, as since it is a 845 Series, I dont Believe that you even have the "Core-Cell" Chip on your Motherboard ..I suggest that you use "Speed-Fan" as this seems to be the Utility that Most of the Members have Success with, and if you want a Utility to Overclock your FSB with, Download Clock-Generator, at http://www.cpuid.com  .....Sean REILLY875

  • Fuzzy Logic 4 and MS-6368

    Hello, I have been unable to get Fuzzy Logic 4 to work with my MSI MS-6368 mothermoard, is this motherboard compatible with Fuzzy Logic 4?
    Thanks
    Ben

    I did it! Both programs are working now! Well, they start and give info   . I uninstalled both applications. After that I removed every line in the registry that had anything to do with the programs.
    I then installed the versions downloaded from the MSI site and after a restart the errors are gone.
    I have to agree with mistawiskas. Fuzzy Logic is a bad piece of software. Trying out other FSB settings in the CMOS works faster and easier. After the lockups created by FL (and very often no reboot as is meant to happen) the settings it suggested are gone.
    PC alert just does what it's meant to do. Though I've seen better programs for that.
