yeah closed loop i.e. phase locked loop

Are you are doing velocity feedback via some type of data acquisition card? Or is this all simulation?

ibrahim on 13 Nov 2012

nah, is all simulation in simulink

There are plenty of tutorials for this already, just look for those related to velocity feedback control:

If you don't need the derivative control (in order to improve damping) just set the appropriate gain to zero.

thanks for ur help so far, but i am not controlling velocity, i am controlling the speed of a stepper motor using PLL. i have managed to get the model of the PLL but the problem now is how to include the stepper motor and stepper motor driver into the model in order to control the speed for simulation.
