Hi everyone, I have a problem in my project. It's about Fuzzy Gain Scheduling of PID controller for BLDC motor. I’ve done with Simulink simulation. But the output response still not good. The overshoot came when I change the set value. I attach the result on the link below. I hope someone can give me the suggestion what I have to do. Thanks a lot.

Look at the control request your controller is generating. The type of response you are getting might be due to the fact that the controller output is limited, but the integrator in the PID controller "winds up" and take a while to unwind. You may want to try using anti-windup in your controller.
