fuzzy controller with 5 inputs

[Dr_Azar]

Dear

I have two questions:

1. Is there anyway to load or open the files of .fis using matlab in labview?

2. I have fuzzy controllers with 5 inputs but why the fuzzy controller in labview is limited to only four inputs? Is there anyway to build a fuzzy controler with 4 inputs?

Thanks

Hi all

I didn't find the answer in the thread about adding more than 4 inputs in fuzzy logic controller. Please Could anyone help me?

Hey Ahmad,

The Fuzzy Controller VI is limited to only 4 input signals. So, there is not way to connect 5 input signals to the same Fuzzy Controller.vi. Check out the LabVIEW PID Control and Fuzzy Logic Manual (page 128 in particular) for a little more information.

Hope this helps.

Hey Eng.Ahmad

I think it is possible to employ a 5th input for the fuzzy controller (or any number for that matter). It requires editing the (Fuzzy Controller.vi) and (Inferenz4.vi) In the second one the job is not very simple but I think it can be done. You have to add case5 to the case structure that creates all the 4 inputs (and it shall create 5 inputs after editing), you also have to make the big For Loop run 5 times instead of 5 etc... In the Fuzzy Controller.vi you only have to add one set of inputs similar to others. 

I am sorry but I have to admit straight from here that I have not tried to do this as I still do not know how to use this whole "fuzzy business". But if you attempt to do this, please post a reply with the result.

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.
