University of Kashan Soft Computing Journal 2322-3707 2 1 2021 05 23 Control of BLDC Motor by using of FOPID Controller Optimized by Imperialist Competitive Algorithm ICA Control of BLDC Motor by using of FOPID Controller Optimized by Imperialist Competitive Algorithm ICA 2 11 111364 FA Abolfazl Halvaei Niasar Saber Falahati Aliabadi Journal Article 2021 05 23 In this paper a new method for speed control of BLDC motors is proposed. In this method, fractional order PID (FOPID) is used for control of BLDC motor. In order to determine the parameters of FOPID controller imperialist competitive algorithm (ICA) is employed for its high speed and accurate for solve of optimization problems. In order to verify the performance of proposed controller, some simulations have been carried out with different object functions in Simulink environment of MATALB and obtained results have been compared with results of conventional PID. Good performance of proposed controller is validated by results of simulations. In this paper a new method for speed control of BLDC motors is proposed.
