摘要
针对永磁同步电机伺服系统在运行过程中参数变化及负载扰动等问题,分析了滑模变结构控制器设计的原则和方法。将滑模变结构控制与矢量控制相结合,设计了适用于矢量控制位置伺服系统的分段式滑模变结构控制器。试验结果表明分段式滑模变结构控制伺服系统符合定位过程中时间最优化的原则,响应迅速,鲁棒性好。
To solve the problem of parameter variations and load disturbance in servo control system of permanent magnet synchronous motor （PMSM）,the method to design sliding mode controller was analyzed thoroughly.Multi-segment sliding mode controller was proposed,which could improve robustness of the system effectively.Experimental results showed that the system with multi-segment sliding mode controller had good robustness and fast response.
