摘　　要：为了优化内置式永磁同步电机(IPMSM)的驱动控制性能,一种结合公式法和高频信号注入法的改进最大转矩电流比(MTPA)控制方案被提出。该方法能够提高系统的动态性能,同时对电机参数变化具有鲁棒性,实现了快速、精确的MTPA控制。采用的公式法无需使用拟合或泰勒级数近似,在工程上更易实现,也更加精确,采用的高频信号注入法直接将高频信号注入到α、β轴电压中,选择注入信号的频率时无需考虑电流环带宽的影响。仿真结果验证了所提改进MTPA方法的有效性。In order to optimize the drive control performance of the interior permanent magnet synchronous motor(IPMSM),an improved maximum torque per ampere(MTPA)control scheme combining formula method and high frequency signal injection method was proposed.This method can improve the dynamic performance of the system,and at the same time is robust to the change of motor parameters,and realizes fast and accurate MTPA control.The formula method adopted does not need to use fitting or Taylor series approximation,which is easier and more accurate in engineering.The high-frequency signal injection method used directly injects high-frequency signals into theαandβaxis voltages,and selects the frequency of the injected signal no need to consider the impact of current loop bandwidth.The simulation results verify the effectiveness of the proposed improved MTPA method.
