摘　　要：内置式永磁同步电机为充分利用磁阻转矩,常采用MTPA控制策略,直接公式计算MTPA控制策略易受参数变化影响,一些研究者提出了虚拟信号注入MTPA控制策略。传统多虚拟信号注入MTPA控制需要四路虚拟信号注入,计算量较大。文章提出一种新的多虚拟信号注入MTPA控制策略,将传统四路虚拟信号注入减少到两路,极大减少了运算量,同时不影响MTPA控制精度。仿真结果与实验结果验证了该方法的有效性,在不影响MTPA控制精度的条件下,显著减少了计算量,具有更好的应用价值。In order to make full use of the reluctance torque,the interior permanent magnet synchronous motor often adopts the MTPA control strategy.The direct formula calculation of the MTPA control strategy is easily affected by parameter changes.Some researchers have proposed the virtual signal injection MTPA control strategy.Traditional multi-virtual-signals injection control requires four-channel virtual signals injection,which requires a large amount of calculation.The article proposed a new multi-virtual-signals injection control strategy,which reduced the traditional four-channel virtual signals injection to two channels,which greatly reduced the amount of calculation and does not affect the MTPA control accuracy.Simulation results and experimental results verify the effectiveness of the method.The amount of calculation was significantly reduced,without affecting the control accuracy and it has better application value.
