本文介绍了间接转矩控制(ISC)的基本原理,分析了基于异步电动机预测模型的间接转矩控制系统的组成及实现方法,给出了ISC的控制算法和电机预测模型,以及该系统的实时控制实验结果。实验结果表明,ISC 控制策略能够有效地改善直接转链矩制系统的低速特性。若ISC和DTC相互配合,可以实现异步电动机直接转矩控制系统在全速范围内的高性能运行。

The principles of Indirect Stator-quantities Control （ISC） is proposed in the paper. Based on predicting models of induction machine, the ISC control system is completed. The structure of induction motor dreive system is shown, and the experiment results are presented. The experiment results show that control performance has been improved by means of ISC in low-speed operation, it is concluded that the proposed controller produces better dynamic performance together with the conventional DSC controller in the overall operating conditions .
