Simulation of self tuning PID controller for dc motor speed control

Abstract

This project describes speed control of separately excited DC motor using Chopper as power converter and PID controller as current controller tuned using fuzzy self tuning PID . The separately excited DC motor can becontrolled 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 using MATLAB. The simulation is doneand analyzed under varying speed and load torque conditions like rated speed and load torque, half the rated load torque and half speed .
