This paper describes speed control of separately excited DC motor using Chopper as power converter and PI as speed and current controller. The separately excited DC motor can be controlled from below and up to rated speed . Optimization filter of speed is obtained using Modulus Hugging Approach . After obtaining the complete model of DC drive system, the model is simulated by MATLAB. The simulation is done and analyzed under varying speed and varying load torque conditions like rated speed and load torque, half the rated load torque and half speed .
