摘  要：针对永磁同步电机这种多变量、非线性、强耦合的控制对象,应用逆系统方法,将永磁同步电机解耦成二阶线性转速子系统和一阶线性磁链子系统；在此基础上,采用鲁棒伺服控制器对伪线性子系统进行线性闭环控制设计。仿真试验表明，这种控制策略能够实现永磁同步电机转速和定子磁链之间的动态解耦控制，并且系统具有良好的动静态性能。

Abstract: A decoupling control approach based on inverse system method had been applied for the permanent magnet synchronous motor(PMSM),which was multi-variable,nonlinear and coupled system.PMSM was decoupled into second-order linear speed subsystem and first-order linear flux subsystem.The servo robust controller was used to design linear closedloop controller for the pseudo-linear subsystems.Simulation results showed that this kind of control strategy could realize dynamic decoupling control between speed and flux of PMSM,and the control system had fine dynamic and static performance.
