The model simulates Chopper fed DC motor drive for speed control of DC motor. Actual speed is compared with reference speed command and error is manipulated by a PI controller whose output is the duty cycle. Duty cycle in converted in PWM by comparing the duty cycle voltage with sawtooth waveform. Pulses are applied to MOSFET controlling the chopper circuit. Chopper circuit is basically a first quadrant buck converter.

My homework is to analysis the function of Chopper Fed DC Motor Drive's every part.But my teacher shows that the model is contrling the speed and the current simutaneously.Anyway ,thanks!
