programming fuzzy logic controller design

[samerham1]

Hi,

please i am using fuzzy logic controller design. Inputs and outputs data are connected to an OPC server.

My question is: could i access programmatically (in the vi ) to the fuzzy logic controller design to prevent to enter in it each time that i need to change values ?

Hey,

If you are using the NI Fuzzy Logic VIs the controler parameters are stored in a file. In that case its not possible to access or change these programmatically.

Hi

If I understood  your question correctly you want to change the fuzzy system properties in run time and I think it is feasible within the same subVI that you access to your fuzzy system.

There is an input to this subVI called "Controller data" it is actually a cluster which contain the properties of the system and you  can manipulate it before starting the fuzzification stage of your sysem.

I hope this will help.

Best regards

Afshin

Hello all

The PID and Fuzzy Logic Toolkit 2009 was completely redesigned.

There are new API VIs and a more intuitive user interface for creating controllers.

You can create MIMO controllers with unlimited inputs and outputs, and also modify the controller on-the-fly.

Check it out the new features and let us know your needs on Fuzzy control.
