| 摘 要： | 时变扰动环境下，永磁同步电机(PMSM)采用鲁棒性较好的滑模控制。根据滑模控制中传统指数趋近律，提出一种改进型的趋近律，并基于改进型趋近律设计了一种PMSM调速系统的滑模速度控制器，提高电机的运行性能。通过仿真结果对比分析，设计的基于改进型趋近律的滑模速度控制器不仅可以提高系统的动态性能，而且削弱了系统的抖振现象，使电机在时变扰动下仍具有较高的运行性能。

| Abstract: | For Permanent Magnet Synchronous Motors(PMSM) in a time-varying disturbance environment, the sliding mode control with better robustness is adopted, an improved reaching law is proposed based on the traditional exponential reaching law in sliding mode control. Based on the improved reaching law, a sliding mode speed controller of PMSM speed regulation system is designed to improve the running performance of the motor. Through comparative analysis of simulation results, the sliding-mode speed controller based on the improved reaching law can not only improve the dynamic performance of the system, but also weaken the chattering phenomenon of the system, and it can make the motor still have high running performance under time-varying disturbance. |
