In this work, a comparison study of using PSO and BFO methods for the tuning of PID controller for speed control of a BLDC motor. Obtained through simulation of BLDC motor, the simulation results show that the proposed controller can perform an efficient search for the optimal gains of PID controller. By comparing between PSO method and BF technique, it shows that PSO method can improve the dynamic performance of the system in a better way.
