摘　　要：从一般非线性系统的相对阶定义出发分析了感应电机的可逆性 ,对感应电机变频调速系统应用逆系统方法 ,将这一多变量、非线性、强耦合的复杂对象解耦成转速与转子磁链两个二阶线性子系统 ,并运用线性系统理论对设计的闭环控制器进行控制。仿真结果表明系统具有良好的静态及动态性能。The invertibility of induction motor and the feasibility of the inverse method to speed control of induction motor are studied via the concept of relative degree of nonlinear systems. The induction motor, which is a multivariable, nonlinear and coupled strongly system, is decoupled into independent second order pseudo linear subsystems: speed subsystem and rotor flux magnitude one. Linear controllers are designed for each of subsystems to obtain good static and dynamic performance.
