摘要

针对表贴式永磁同步电主轴(permanent magnet synchronous spindle, PMSS)弱磁控制中随转速升高出现定子电流震荡的问题，本文在分析弱磁控制算法以及转速调节器的基础上，提出一种基于模糊控制的改进型超前角弱磁调速策略。此策略使用改进型超前角弱磁控制算法扩展电主轴调速范围并抑制电流震荡；使用模糊PI转速调节器实现参数的动态调节，提高系统的稳定性。实验结果表明，基于模糊控制的改进型超前角弱磁调速策略能较好的扩展电主轴调速范围，且较好地抑制定子电流的震荡，从而提高永磁同步电主轴弱磁阶段的动态性能及稳定性。

Abstract

Aiming at the problem of stator current oscillation appearing with increase in rotating speed in a surface mounted permanent magnet synchronous spindle (PMSS)’s flux-weakened control,based on analyzing the flux-weakened control algorithm and the rotating speed regulator,an improved leading angle flux-weakened rotating speed regulation strategy based on the fuzzy control was proposed.With this strategy,the improved leading angle flux-weakened control algorithm was used to extend the spindle’s rotating speed regulation range and suppress current oscillation.A fuzzy PI rotating speed regulator was used to realize the parametric dynamic adjustment and improve the system’s stability.The actual test results showed that the improved fuzzy control-based leading angle flux-weakened control strategy can effectively suppress the stator current oscillation to improve the PMSS’s dynamic performance and stability.
