In this paper, an effective controller design for the BLDC motor drive is proposed using nature inspired Whale Optimization Algorithm (WOA). The PI controller is developed for the speed control of BLDC motor using Whale Optimization Algorithm. The gain settings of a PI controller are improved using WOA, with Integral square Error (ISE) as the objective function. The dynamic characteristics of the BLDC motor are observed by the developed model using MATLAB/simulink environment. The suggested controller's performance is evaluated under a variety of load and set speed settings, and it is compared to other known optimization approaches such as PSO and DE. Based on the simulation results, it is clear that the suggested controller performs better under all of the drive's operating conditions.
