摘　　要：提出了一种比例谐振(Proportional Resonant,PR)控制器的改进模型,将其应用于永磁同步电机控制中.用改进的PR控制器替代传统的PI控制器,节省一次坐标变换,省去了受温度及电机参数影响的交叉解耦项和前馈补偿项,简化了控制算法.仿真和试验结果表明,引入改进PR控制器的永磁同步电机控制系统控制性能优越,能够实现对交流输入信号的无静差跟踪,系统对低次谐波以及指定次谐波具有很强的抑制能力,具有重要的实用价值.This paper proposed an improved proportional resonant（PR） controller, which was applied to the permanent magnet synchronous motor control system. Compared with the traditional PI controller, it can not only make the whole control system save a tedious coordinates transformation, but also remove cross-decoupling compensation and feed forward compensation influenced by temperature and electrical pa- rameters, thus simplifying the control strategy. Simulation and experiment results show that the introduc- tion of the improved PR controller to permanent magnet synchronous motor control system can achieve ze- ro static error with the AC input signal, ant the system has a strong inhibitory ability in low-order har- monic and designated harmonic.
