摘要 针对传统矢量控制系统对电机参数依赖性较大的特点,对传统反馈解耦的矢量控制方法进行了改进。在电压解耦的矢量控制系统中,利用磁链观测获得的电机磁链实时计算解耦电压,并在解耦结构中增加电流误差修正的PI控制,以克服由于电机参数变化对PMSM矢量控制系统的影响。仿真结果表明,改进的矢量控制方法能提高系统的解耦效果,增强系统的调节能力以及对电机参数变化的鲁棒性,证明了控制方法的正确性和有效性。 For the traditional vector controlled permanent magnet synchronous motor(PMSM) system is sensitive to the parameters of the machine,a modified vector control method was presented.In order to overcome the influence of the variation of the parameter on the PMSM vector control system,flux linkage got by the modified stator flux linkage observer was used to computing the decoupling voltage instead of the fixed inductance and the flux linkage excited by the PM in the air-gap used in the traditional vector control system,and the PI controller for current error compensation was applied in the control system.The simulation results show that the modified vector control method can improve the effect of the decoupling,enhance the regulate capability and the robustness to the parameters of the system,the correctness and validity of the control method is proved.
