The Research of Solving Robustness of Vector Control System by Adaptive Inverse Control Method

针对一般矢量控制系统存在的电动机参数鲁棒性差这一难题,首次将不同于常规反馈控制的新型控制策略自适应逆控制引入感应电动机变频调速系统,提出一种感应电动机变频调速系统新型控制结构,有效地解决了电动机参数时变对系统性能的影响。理论分析与仿真实验表明所提方案的有效性与合理性。

In vector control system there are two problems, i. e., dynamic system existent the coupling between torque subsystem and magnetic field subsystem so that it can＇t realization whole decoupling, the weak robustness to machine parameter time-varylng at static state. To solve these problems, adaptive inverse control strategy for the first time is introduced in the paper. The theoretics and the experiments demonstrate that the strategy can effectively solve the influence of coupling between torque and magnetic field in Vector Control System to dynamic and static state performance of the system.
