COMPARISON OF SLIDING MODE AND PROPORTIONAL INTEGRAL CONTROL FOR BRUSHLESS DC MOTOR
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 8
Abstract
This paper will compare properties of Sliding Mode Controlled (SMC) and classical Proportional Integral (PI) controlled brushless DC motor (BLDC) in applications. It is the simple strategy required to achieve good performance in speed or position control applications. This paper addresses controlling of speed of a BLDC motor which remains among the vital issues. A BLDC motor is generally controlled by Proportional plus Integral (PI) controller. PI controller is simple but sensitive to parameter variations and external disturbance. Due to this reasons, Sliding Mode Control (SMC) is proposed in this paper. This control technique works against parameters variations and external disturbances, and also its ability in controlling linear and nonlinear systems. Performance of these controllers has been verified through simulation using MATLAB/SIMULINK software. The simulation results showed that SMC was a superior controller than PI controller for speed control of a BLDC motor
