In this paper a comparative study on speed control of Brushless DC motor is presented. The mathematical model of the DTC based BLDC motor is developed and it is used to examine the performance of the controllers. Initially a PI controller is developed for the speed control of the given BLDC motor. Then the controller is upgraded to PID, and the performance of the BLDC motor is verified. It is difficult to tune the parameters and get satisfied control characteristics by using conventional PI, PID controllers. This paper proposed an improved Sliding Mode Controller (SMC) to control speed of Brushless DC motor. Through extensive simulations it is observed that the performance of SMC is better than PI, PID controllers. The modeling, control and simulation of the BLDC motor have been done using the software package MATLAB/Simulink.
