Research on Fuzzy Control Strategy of Axially-Laminated Anisotropic Rotor Reluctance Synchronous Motor

针对轴向叠片各向异性(ALA)转子磁阻同步电机开环变频起动存在振荡及直接转矩控制电磁转矩脉动大的问题,设计了Mamdani型模糊逻辑控制系统,建立了仿真模型。仿真结果表明,ALA转子电机在模糊控制下有良好的起动和抗扰动性能;并制作了实验系统,实验结果表明设计的模糊控制器是合理有效的。

Aiming at the problems of oscillation in open-loop variable frequency starting of axial laminated anisotropic（ ALA） rotor reluctance synchronous motor and large electromagnetic torque ripple in direct torque control, Mamdani fuzzylogic control system was designed. The simulation model was established. The simulation results show that the ALA rotormotor has good starting and anti-disturbance performance under fuzzy control. Experimental system was built ,experimentalresults show that the designed fuzzy controller is reasonable and effective.
