摘　　要：针对永磁同步电机(PMSM)传统PID位置控制中速度不可控且PI参数整定复杂的问题,文章提出了一种基于反推原理的PMSM速度指定位置跟踪最大转矩电流比(MTPA)控制方法。相较于id=0控制,MTPA控制能够有效利用凸极永磁同步电机(IPMSM)的磁阻转矩实现电机出力最大化,且仅需最小电流。文章采用公式法建立了MTPA控制下的dq电流关系式,然后设计了位置、速度和电流反推控制器,这样可以增加一个速度控制自由度,同时保证了控制系统的稳定性。仿真结果表明,该控制系统动态响应快、稳态误差小和参数调整少,从而验证了该方法的正确性和有效性。In response to the problem of uncontrollable speed and complex PI parameter tuning in traditional PID position control of permanent magnet synchronous motor(PMSM),this paper proposes a PMSM speed specified position tracking maximum torque current ratio(MTPA)control method based on the principle of backstepping.Compared to id=0 control,MTPA control can effectively utilize the reluctance torque of salient pole permanent magnet synchronous motor(IPMSM),achieve maximum motor output,and only require minimum current.The article uses formula method to establish the dq current relationship under MTPA control,and then designs a position,speed,and current backstepping controller,which can increase a speed control degree of freedom while ensuring the stability of the control system.The simulation results show that the control system has fast dynamic response,small steady-state error,and few parameter adjustments,thus verifying the correctness and effectiveness of the method.
