We are simulating a Single Phase DC Brushless Motor using Simulink/Matlab. We have made a motor model in simulink. Now, we would like to control the input current pulse using Pulse Width Modulation(PWM). As of now we are just beating around the bush debating on whether to use a PID or PWM for Control.

Please let us know what's the right/suitable approach if not the algorithm.

Thanx,

Kumar.
