摘　　要：为了简化对转永磁同步电机(PMSM)的结构,提高其工作性能,研究了该种电机的无位置传感器控制技术。结合面贴式对转PMSM的性质,建立了其数学模型,利用电机稳态时双转子转速相等的特点,提出了一种基于高频脉振电压信号注入的转速估算方法。设计了转速跟踪观测器,建立了对转PMSM的仿真模型和无位置传感器矢量控制系统。仿真结果与理论分析相吻合,表明该系统可使面贴式对转PMSM在全速域内实现无位置传感器控制,系统跟踪准确,响应迅速,鲁棒性强。To simplify the configuration of counter-rotating permanent magnet synchronous motor（PMSM） and improve its working performance, a non-position-sensor control technique for counter-rotating PMSM is studied. A mathematic model for counter-rotating PMSM is deduced according to the character of surface-mounted PMSM. A speed estimation method is proposed based on high frequency voltage pulse injection according to equal speed of inner and outer rotors in steady state. Moreover, a speed tracking observer is designed, and both simulation model and non-position-sensor control system of counter-rotating PMSM are established. Simulation results agree well with theoretical analysis, which verifies that the proposed strategy is competent for non-position-sensor control of surface-mounted PMSM in full speed scope with accurate tracking performance, high robustness and quick response.
