Abstract

 
This paper presents the closed loop control of dc motor using chopper with PID controller in first & second Quadrant. The aim of the paper is to explain the design optimization along with low cost implementation of the controller circuit. The design of firing circuit and the controller circuit is done by using low cost components. The parameters of 0.5HP Separately Excited DC Motor are found out and the power circuit is designed using MOSFETs for the motor parameters. First the firing circuit is tested in open loop system to run the motor, and then First Quadrant operation is successfully implemented using closed loop system. The feedback for closed loop system is taken from a dynamo connected to the shaft of the motor. Finally the Two Quadrant operation of Chopper is successfully implemented and got the results by using an optimized low cost firing and controller circuit.

Keywords: DC motor, PWM circuit, PID controller, Driver circuit
