Optimal Tuning of Fuzzy & PID Controllers for BLDC Motor Speed Control via HHO Algorithm

Design of PID and Fuzzy controller for speed regulation of brushless DC motor is presented in this paper. The controller parameters kp, ki, kd are optimized based on hawk’s harris optimizer (HHO) algorithm. The optimized coefficients keep in track with zero error signals. The output of the controller is given to the variable dc source which varies the input voltage to the three phase inverter depending on the input signal. The three phase inverter gives the voltage to the BLDC motor which enhances the stability of the system. The effectiveness of the controller is demonstrated by simulation that In comparison with PID, Fuzzy is more flexible and trustworthy to control higher order systems. Simulation results give validation of the proposed work and provide effectiveness of fuzzy controller in terms of robustness, stability and control effect as compared to PID controller.
