Abstract: The BLDC motors are used in automatic systems for trajectory tracking, motion control, etc. If any external disturbances and set point variations occurs, conventional controllers are unable to track the set point accurately. Hence, adaptive controllers are proposed to overcome this issue. The paper focuses on the development of model reference adaptive controller (MRAC) technique for speed control of BLDC motor. The MRAC approach is implemented with the conventional PID controller. The control strategy is simulated and investigated using MATLAB/Simulink. Simulation results of the PID, fuzzy-PID and MRAC-PID have been presented and the performances of the controllers are analysed on the basis of various control system parameters such rise time, settling time and peak overshoot. The results demonstrate that the proposed controller gives a good dynamic behaviour, perfect speed tracking with minimum overshoot. The developed controller is implemented in real-time using DSP processor and the respective PWM pulses are acquired for different ranges of speed. Experimental results prove the effectiveness of the proposed control approach.
