This simulation is useful to understand the close-loop speed control of induction motor using volt/hz method using the contol of sine pulse width modulation.
I hope it is very helpfull to you.

If you can download this model file please change the value of kp and ki in PI controller.
Kp=1. & Ki=0.7.
why after 0.7 sec the rpm wont constant anymore
Speed as ramp input is not valid
your actual speed of motor is continious changing and ref. N are also changing so its not valid and its give error in programming.
because of these always take ref. speed as constant.
does it valid for ref speed as ramp input??
Updated newly calculated value as per the theory.
Error is solved
