基于逆系统理论的感应电动机解耦控制的研究

应用多变量非线性控制的逆系统理论，对感应电动机变频调速这一多变量、非线性、强耦合的控制对象进行解耦控制，从而将其分解为转速和转子磁链两个线性子系统，并应用线性系统理论对其进行综合。研究表明，这种新的控制策略实现了感应电动机转速与转子磁链的动态解耦。论文的最后给出了仿真结果。

Inverse System- Based Decoupling Control of Induetion Motor

A decoupling control approach based on dynamic inversion has been developed for in-duction motor' s adJustable-frequency drives. Firstly, the theory of inverse system is briefly intro-duced. Then the detailed discussion of decoupling control for induction motor is given. To verify theperformance of the control scheme, some simulations have been employed, and the results are satis-factory. Finally, the authors draw the conclusion that decoupling control based on inverse system the-ory has the characteristic of simplicity as well as practicability and successfully realizes the dynamic de-coupling of rotor speed and rotor flux linkage.
