摘要
针对同步电机控制系统非线性、强耦合以及模型不确定等特点,提出了基于模糊控制策略的直接转矩控制方法.利用MATLAB/SIMULINK软件对永磁同步电动机直接转矩模糊控制系统进行仿真分析,建立了定子坐标系下永磁同步电动机控制系统的数学模型.对永磁同步电动机直接转矩控制进行了理论分析,并将模糊控制技术应用于控制系统中.给出了同步电机直接转矩控制的仿真结果,分析结果表明,该系统采取的模糊控制策略有效地改善了系统的控制性能.
Direct torque control based on fuzzy strategy was proposed for permanent magnet synchronous motor （PMSM） with nonlinear, strong coupling and uncertain model. The direct torque fuzzy control of PMSM was analyzed by MATLAB/SIMULINK. Mathematic model of PMSM control system was built in stationary reference frame. The theoretical analysis of direct torque control for PMSM was discussed, and fuzzy control was applied to the system. Some important implementing methods were presented. Simulation results show that the adopted fuzzy control algorithm can improve performances of system.
