摘要:
为提高低速时内置式永磁同步电机（IPMSM）转子位置辨识的精度，设计一种新型信号解调方案。当注入旋转高频电压信号后，所采用的新型二阶广义积分器（SOGI）可对响应电流id和iq进行解调，随后经锁相环（PLL）获取转子位置和转速。经仿真验证，相较传统滤波器法，新型SOGI方法有更高的观测精度。
Abstract:
In order to improve the accuracy of rotor position identification of interior permanent magnet synchronous motor (IPMSM) at low speed, a new signal demodulation scheme is designed. When the rotating high-frequency voltage signal is injected, the new second-order generalized integrator (SOGI) can demodulate the response currents id and iq, and then obtain the rotor position and speed through a phase-locked loop (PLL). It is verified by simulation that the new SOGI method has higher observation accuracy than the traditional filter method.
