| 摘 要： | 文章针对转子磁场定向d-q坐标系下的4阶异步电动机的模型,运用非线性解耦线性化理论,把异步电动机调速系统分解成磁链和转速两个子系统,实现了磁链和转速的完全解耦。采用调节器最佳整定方法,设计了磁链和转速控制器。仿真结果证明该控制器具有良好的稳、动态性能,能对磁链和转速进行高性能的控制。

| Abstract: | In this paper,exact decoupling of the flux-linkage and speed was realized by the method of nonlinear decoupling based on the four-order model of an induction motor under the field-oriented d-q coordinate frame.The induction motor model was decoupled into two independent linear subsystems of flux-linkage and speed subsystem.Optimal controllers for flux-linkage and speed loops were designed to achieve desired dynamic and steady state responses.Simulation results showed that a good performance of the drive system with the designed controllers. |
