感应电动机的解耦控制与矢量控制的解耦性质

Decoupling and Vector Control of Induction Motor

对感应电动机的解耦控制及矢量控制的解耦性质进行了研究 .从感应电动机变频调速系统的非线性模型出发 ,分别利用非线性控制的状态反馈线性化方法和转子磁场定向方法对系统进行了讨论 .研究结果表明 ,感应电动机的矢量控制只能实现电机转速与转子磁链之间的静态解耦 ,不能实现二者之间的动态解耦 ,而基于状态反馈线性化的解耦控制方法 。

Decoupling and vector control (field oriented control) strategies are studied for induction motor. The former uses dynamic feedback linearization approach based on dynamic inversion, and is able to realize dynamic decoupling between the rotor speed and the rotor flux linkage.While the latter utilizes field oriented control methad, and could only realize static decoupling.Simulations are employed for verification.
