| 中文摘要 | 介绍了一种基于脉振高频电压信号注入的永磁同步电机转子位置和速度估算方法,并以此为基础实现了永磁同步电机的无速度传感器矢量控制系统。无论是内埋式还是表面贴式永磁同步电机,其交直轴高频阻抗都可以表现出凸极效应,当脉振高频电压信号注入到定子线圈中时,相应的高频电流信号将包含有转子的位置信息,用一种合适的算法可以提取这一信息。在高速和低速(包括零速)运行时,这种方法都可以精确地估算出转子的位置。最后,以内埋式永磁同步电机为例,给出了这种方法的仿真结果,验证了这种方法的有效性。; A method for estimation of the rotor position and speed of PMSM by using the fluctuating high-frequency voltage signal injection was described. A scheme of sensorless drive of PMSM can be realized by using this method.In the surface-mounted PMSM(SMPMSM) and the interior PMSM(IPMSM),d-and q-axes high-frequency impedances are different.When the flucluating high-frequency voltage signal is injected into the stator coils of PMSM,the corresponding high-frequency current signal includes the information of the rotor position,an appropriate carrier signal extraction and a spatial saliency tracking scheme are developed for sensor-less control.Rotor position can be estimated accurately at standstill and high speed by using this method.The simulation results show the feasibility and effectiveness of this algorithm. |
