基于模糊预测控制的无刷直流电机控制研究

摘要

针对传统控制方法在对永磁无刷直流电机(Brushless DC Motor,BLDCM)进行控制时鲁棒性差、精度低、实时性不理想等缺点,提出了一种模糊与预测相结合的控制算法。将该算法应用于永磁无刷直流电机双闭环调速系统的转速闭环中,并利用 MATLAB 软件搭建无刷直流电机的控制系统进行仿真。实验结果表明该算法利用模糊控制与预测控制各自的优点,提高了无刷直流电机的性能,是可行和有效的。%When the Brushless DC Motor(BLDCM)is controlled by traditional methods,it is weak in robustness,accuracy and real-time .A fuzzy predictive control method is proposed in this paper.The control algorithm is applied in the double loop of speed servo system of BLDCM.The control system of Brushless DC motor is built and simulated by the MATLAB software.Ex-periments results show that the control algorithm combines the advantages of the fuzzy control and the predictive control and im-proves the performance of the BLDCM.This control method is proved to be feasible and effective.
