The objective of this paper is to compare performance between two type of controller for BLDC motors. BLDC motors are one of the motor types rapidly gaining popularity. The major problem in BLDC drives are that some disturbances are originated in the drive which will reduce the stability of the system. Conventional controller is used to control the speed of the motor, but the response of the system is affected by steady state error and gives a poor transient response. So we use a Linear Quadratic Regulator controller to regulate the speed of the motor. In this paper LQR based controller is designed and its performance is compared with traditional PID controller using Matlab and Simulink.
