| 摘 要： | 针对现有永磁同步电机的直接转矩弱磁控制,难以做到实时监测负载条件和参数变化,只能在空载时实现全速运行问题,文中给出一种基于模糊控制理论的弱磁控制算法。该算法基于实时转速和转矩的变化,根据模糊理论智能地调节直接转矩控制中的磁链给定值,从而实现弱磁控制。通过Matlab/Simulink仿真验证了算法的正确性。

| Abstract: | Flux-weakening control of permanent magnet synchronous motor (PMSM) is a hotspot of motor research.However,the objectives of monitoring load conditions and parameters changes real time cannot be achieved by the existing PMSM direct torque flux-weakening control method at full speed only with no-load running.This paper puts forward a new method of flux-weakening control based on fuzzy control,which can intelligently adjust the value of reference direct torque control flux according to the changes of the real-time speed and torque value.The Matlab/Simulink simulation verifies the accuracy of intelligent flux-weakening control of the permanent magnet synchronous motor direct torque control. |
