摘要
首先介绍逆系统的一般原理,然后针对异步电动机这一非线合、多变量的控制系统,采用逆系统的方法进行分析,通过给定不同的条件,选择不同的输入和输出,论证系统的逆性。进一步分析,发现转差频率矢量控制和磁链反馈矢量控制分别为逆系统解耦控制的一类实现。最后文章给出一类逆系统线性化的实现,并附以仿真结果。
At first,the general principle of inverse system is introduced. And then,applying this principle the induction motor which is a nonlinear,strongly coupling and multivariable system is analysed. By giving different conditions and choosing different input and output variables,the invertibility of the system is proven. Further analysis shows that both the slip frequency vector Control and the rotor flux linkage feedback vecter control are all of the realization of inverse-system decoupling control. Finally,the implementation of inverse-system linearization and the simulation result is given.
