摘　　要：为改善无刷直流电机的调速性能,研究了基于模糊控制思想的模糊控制器及其在BLDCM控制系统中的应用。在Matlab仿真平台下,建立了BLDCM的模型,构建了BLDCM转速闭环控制系统,其中转速控制器分别采用了模糊控制器和普通PID控制器。仿真结果表明:与常规PID控制器相比,采用模糊控制器的优势在于转速输出无超调、响应速度快、控制精度高,具有较强的鲁棒性和自适应能力。In order to improve the speed performance of BLDCM, the paper investigated fuzzy controller used in BLDCM control system. Based on Matlab, the model of BLDCM was built up as well as the simulation system of BLDCM with speed loop controller. The speed loop was controlled under different control strategies-the fuzzy control and common PID control respectively. The simulation results showed that the control system with fuzzy control had faster dynamic response, higher precision and more adaptive performance than that of the normal common PID without overshooting at all.
