Due to the good performance of brushless motor, its application is widespread. Brushless DC motor has following advantages that are low interference, low noise, high efficiency and so on, so it was widely used in industrial and control field. But DC motor has larger current commutation torque ripple, greatly reduce their reliability and stability. This design using direct torque control strategy to reduce torque ripple, and compares the control results of PI controller with direct torque control method. In the process of regulating motor’s speed ，When adopts PI controller here has great overshoot and start time of speed is long than direct torque control, current pulse obviously severe than direct torque control. The simulation results show that overall effect of direct torque control is superior than double closed loop control. It fully explains that the control strategy in this paper is effective.

Speed Regulation

Brushless DC Motor (BLDC) is gaining more and more popularity as one of the best electrical drives nowadays due to advantages like high efficiency, low maintenance, good reliability & wide dynamic response. The traditional brushed motor speed regulation is essentially effective in low speed and unable to lower the commutation torque ripple in high speed range. Speed regulation of Brushless DC (BLDC) motor is done by utilizing PI controller. The PI controller output act as  the input to the variable voltage block. The mathematical modeling of BLDC motor is additionally shown here. The BLDC motor is supplied from the inverter while the rotor position and speed are the input here. The detailed mathematical model of the anticipated drive system is developed and simulated using MATLAB/Simulink environment.  Principle of operation of using component is examined and therefore the simulation results are reported here to verify the theoretical analysis.
