摘　　要：凸极同步电动机是个非常复杂的多变量、强耦合的被控对象。针对前馈解耦控制的不足,将先进的内模控制理论应用在同步电动机交直交变频调速系统定子电流环的控制中,所设计的内模控制器对定子电流交叉耦合电势具有动态解耦作用,且只有一个调节参数,在线调节方便,参数调整与系统的动态品质关系明确。计算机仿真结果表明,它与传统的前馈控制相比,具有更好的动态性能。Salient-pole synchronous motor is a very complex multi-variable and strong coupling object. Owing to the deficiencies of feedforward decoupling control, the advanced internal model control （IMC） theory was used in synchronous motor AC-DC-AC variable frequency system stator current loop control. IMC controller was designed to dynamic decoupling of the stator current cross-coupling potential, there was only one adjustable parameter, online convenient adjustment. Further more, parameter adjustment had a clear relationship with the dynamic performance. The computer simulation results show that comparing with the traditional feedforward control, it has a better dynamic performance.
