带负荷观测器的交-交变频同步电动机矢量调速系统的动态性能分析

DYNAMIC PERFORMANCE ANALYSIS OF CYCLOCONVERTER-FED VECTOR CONTROL SM SYSTEM WITH LOAD OBSERVER

交 -交变频同步电动机矢量控制常用于像连轧机一类的调速系统 ,此类系统对动态性能有较高的要求 .本文分析了基于负荷观测器的负载扰动前馈控制对该系统动态性能的改善作用 ,并建立了一套仿真软件包 。

The vector control of cycloconverter-fed synchronous motor is usually used in drive systems such as tandem mills,which demand high dynamic performance.The improvement of the system dynamic performance with a load-observer-based load disturbance feedforward control is shown.Besides,a simulation software package was developed,and used to verify the validity of the theoretic analysis.
