Simplified Method of Speed Control of a DC Motor through DAS Using MATLAB-Based PID Controller and Study of its Application in a Voltage Control System of a DC Generator

A PC based speed control system of a PMDC motor using PID controller with the help of Data Acquisition System has been designed in order to control the process variable to achieve the most efficient control in the plant operation. The proposed PID controller has been tested with a process plant analogue and implemented it, in the speed control system of a PMDC motor and voltage control system of a DC generator where DC motor is coupled as a prime mover. The characteristics of the proposed controller along with process plant analogue have been studied. The speed control characteristic of the DC motor with the controller set point and load characteristics of the DC generator with and without this controller have been determined experimentally and reported in this paper.
