摘　　要：交流电机高性能调速系统中,间接矢量控制系统控制方法比较简单,不需要进行磁通检测,而像通常的转差控制方法一样,只要测出电动机转子频率,加上根据需要的转矩推算出应有的转差频率,以此控制定子电流的瞬时频率,就能使电动机的电流和转矩迅速由原先的工作状态变到新的所需工作状态。本文利用Matlab/Simulink对间接矢量控制系统进行研究,结果表明系统稳定,并具有较好的静动态性能。In the high performance system for AC drive, the structure of indirect vector control system VCS is simple. It is not indispensable to measure flux. It is only indispensable to measure rotor frequency and calculate the slip frequency to control the frequency of the stator current. It makes the current and toque change from primary state to a new required state. In this article, the modeling and simulating were performed on the indirect VCS using Matlab/Simulink. The simulation result showed that the system is stable, realizes decoupling of flux and torque and has better static and dynamic characteristics.
