Abstract:

Speed control of Brushless DC (BLDC) motor based on conventional control schemes are commonly used. Despite the fact that PI controllers maintained the steady state accuracy, these controllers pose difficulties such as load disturbances and parametric variations. FLC offers better speed response at dynamics and cancels disturbance impacts when load torque change.To improve control performance and integrate the benefit of these two controllers, a hybrid controller is included in this comparative study. The performance of the hybrid controller is obtained with two schemes Logical switching based-on error and Smart blending based-on system states. The dynamic characteristics of speed and torque of the drive system are effectively evaluated and compared for different operation modes. Results showed that Smart blending scheme is better in generally for most of the performances. The modeling and simulation of the speed controllers have been done in MATLAB/SIMULINK environment.
