Hello everyone,

I'm designing a FLC for speed control of pmsm using simulink. I want to know how to set the ranges the input and output of FLC as my reference speed signal ranges from -1000:0:1000 and the load across the motor drive is 0--15Nm.

I have studied different paper related to FLC for speed control and tried to setup the membership functions and fuzzy rule but during test its shows wrong result and the actual speed of motor drive doesn't track the reference speed. The same simulation model with PI speed speed control is working effectively well but with employing FLC the response of the drive show wrong result.

So i need some guidance in this regards.

Thanks
