速度环制约着伺服系统的动态性能,文中给出了永磁同步电机伺服系统速度环调节器的设计,并通过理论推导和仿真分析了调节器参数和负载扰动对其性能的影响。针对该问题提出了通过负载前馈补偿有效改善速度环性能的方法,设计了相应的负载观测器,并经仿真加以验证。

The speed loop of permanent magnet synchronous servo system is optimized in this paper. On the basis of current loopwith excelent performance, the speed loop is designed. The analysis and simulation show that parameters of the speed controller and load disturbances district the dynamic performance of the system. Then the feedforward compensation through load observer is provided to improve the characteristic of the system, which is validated by simulation in the end.
