| 摘 要： | 针对异步电动机调速系统中磁通和转速的动态解耦在实际实现时较难处理的问题，在研究非线性状态反馈控制算法的基础上，根据二阶系统性能响应指标提出了该控制算法中比例控制器增益的选择方法。由Matlab软件中的SimPowerSystems工具箱构建出仿真框架并把该算法嵌入到其中进行仿真，结果表明该方法与普通FOC矢量控制方法相比，转速和磁通的动态解耦效果明显改善。

| Abstract: | We propose selecting the gains of proportional controller on the basis of research on nonlinear State-Feedback Control Algorithm in view of the difficulties in implementing the dynamic decoupling between the flux and speed of induction motor timing system.We perform a simulation with the SimPowerSystems toolbox of Matlab and the algorithm.It shows that the algorithm can achieve much better decoupling effect between flux and speed than FOC control algorithm. |
