600 brushless (BLDC) motors are one of the electrical drives that are rapidly gainingpopularity, due to their high efficiency, good dynamic response and low maintenance. In this project from the speed controller has been designed by using two types of control strategies First one addresses the PID (Proportional, Integral Derivative) controller based on pole placement technique and the second one addresses about the IMC (Internal Model Controller). The simulation results are carried out by using MATLAB / Simulink successfully for closed loop operation of the three phase BLDC motor so that the motor runs very closed to the reference speed. The performance parameters are compared for both the control strategies for speed control of BLDC motor drive. The results presented Validate the motor control strategies for improving performance.
