A PID Controlled Real Time Analysis of DC Motor

Saurabh Dubey , Dr. S.K. Srivastava

Conventional PID controllers are used to control the dc motor for various industrial processes from many years due to their simplicity in operation. PID controllers require mathematical models to control the plant for different process control applications. In this paper worked out, speed control analysis of DC motor using PID controller. Speed control of separately excited dc motor is done using armature voltage control method. PID controller basics are briefed and various tuning methods of PID controller are explained. Mathematical modelling of dc motor is done and is simulated in Simulink. The control system consisting of PID controlled dc motor is also simulated in Simulink. Response of dc motor is recorded as simulation result when step input is provided as reference signal. Thereby, performance analysis of dc motor with PID controller is performed by calculating various response parameters such as maximum overshoot, rise time, settling time, etc.
