摘　　要：针对非线性感应电机变频调速系统解耦控制方案存在的误区进行了深入研究,通过微分反馈线性化、逆控制、矢量控制这三种线性化解耦方案的对比研究表明,只有矢量控制对非线性感应电机施以有效控制,得出不应单纯地从数学角度将非线性系统解耦、线性化作为参数具有时变特点的电机系统最终控制目标的新结论。To solve the problem of the misleading in the non-linear induction motor vanable-trequency clnvlng system with decoupling, an deep research is carded out. The derivation-feedback, inverse control and vector control which are used to decouple and linearize are compared and researched, the results indicate that derivation-feedback and inverse control which depends on mathematical equation to decouple the system has time-varying and exterior disturbances. So the vector control is the most effective method to control the induction motor now days.
