摘　　要： 提出了永磁同步电动机考虑参数变化时精确的感应电势关系式新模型,建立了微分型和非微分型两种高精度感应电势观测器,证明了感应电势观测器的稳定性和收敛性,分析了参数变动对位置估计的影响.针对无位置传感器矢量控制系统,以内埋式永磁同步电动机为例进行了仿真实验研究,结果表明设计的感应电势状态观测器具有优良的性能. Taking parameter variation into account, a new model of the induced electromotive force relation of a permanent magnet synchronous motor （PMSM） was presented. Two kinds of induced electromotive force observers with high precision, differential and non-differential, were established. The stability and astringency of the induced electromotive force observers was proved. The effect of parameter variation on their position esti- mation was analyzed. For a sensorless vector control system, the interior permanent magnet synchronous motor for instance was systematically simulated. The results show that the induced electromotive force observers have excellent performance.
