Performance Analysis of Speed Control of Direct Current (DC) Motor using Traditional Tuning Controller

Abstract — The control of the speed of a DC motor is an important issue and has been studied since the early decades in the last century. This paper presents a comparison of time response specification between different controller and Linear Quadratic Regulator (LQR) for a speed control of a DC motor. The goal is to determine which control strategy delivers better performance with respect to DC motor’s speed. Performance of these controllers has been verified through simulation using MATLAB/SIMULINK software package. According to the simulation results the Comparing with PID-ZN controller, PID-MZN controller and PI-PSO controller, the tuning method was more efficient in improving the step response characteristics such as, reducing the rise time, settling time and maximum overshoot in speed control of DC motor. Linear quadratic regulator method gives the better performance and superiority of liner quadratic regulator method over other controller
