Linearization And Decoupled Control for Induction Motors Based on SVM Inverse System

本文提出了一种新的系统线性化解耦控制方法,其特点是不依赖于对象的精确数学模型,通过采用支持向量机与逆系统相结合的方法来构造原系统的逆系统.本文将基于支持向量机逆系统的方法应用于感应电机解耦控制,将感应电机这一多变量、非线性、强耦合的复杂对象动态解耦成转速与转子磁链两个一阶子系统,从而可以像线性系统一样进行控制.仿真结果表明采用该方法后系统具有优良的静态与动态解耦性能.

A novel method named as support vector machine （SVM） for induction motor control is proposed. It is characterized by the construction of the SVM inverse system which is independent of the motor model and parameters. Through using SVM and inverse system integrators, the motor inverse system is built .The multivariable, nonlinear and strongly coupled system is deeoupled into two independent flint-order subs, or rotor speed subsystem and rotor flux one, so as to be easy to control each of the subsystems like linear system. Simulation results show that this system have good static and dynamic decoupling performance.
