摘　　要：为提高永磁同步电机单电流调节器高速运行的转速控制性能,设计了一种用于永磁同步电机单电流弱磁控制的转速滑模控制器。在滑模控制器的设计中选取了积分型滑模面,有效削弱滑模的固有抖振现象,减小了转速误差和抖动,而且电机转速对负载和供电电压的变化不敏感。结合单电流弱磁控制策略,滑模控制器利用电机定子电流d-q轴交叉耦合效应的作用,实现弱磁和转速的集成控制。仿真和数据分析验证了其可行性。An improved sliding mode speed controller was presented for flux-weakening control of permanent magnet synchronous machine （PMSM） based on single current regulation algorithm, to improve the controllability of the speed of the single current regulator. The integral sliding surface was designed, which results in the elimination of chattering and the declination of the speed error and the robustness to parameter disturbance and load variation in the flux-weakening area. Based on the d-q current cross-decoupling effect, the proposed control combined single-current regulator algorithm and sliding mode control. The scheme was verified by computer simulation using PLECS software analysis.
