【Abstract】 Fuzzy control was widely used in brushless DC motor(BLDCM)control.In view of its shortcoming that the control parameters couldn’t be updated in real time, the design of fuzzy controller based on moth flame optimization(MFO)algorithm was proposed for the first time.For the problem that the variables of BLDCM control system were complex and nonlinear, it was difficult to establish specific mathematical model.A modular motor simulation model of double closed-loop control of current and speed was built.The algorithm optimized the quantization factor and scale factor online, and used ITAE to verify the rationality of the fitness objective function.Simulation results show that the proposed method makes the control system has the advantages of small overshoot and high control accuracy.更多还原
