电机车IPMSM高频脉振电压注入法转子位置检测∗

摘要

As the mine electric locomotive traction motor, it is vital to obtain the permanent magnet synchronous motor rotor position information accurately in the control process. Inject the high frequency voltage signal into motor, the rotor angle and speedestimation was estimated by using Luenberger observer, realized the sensorlessoperation of system, and verified by simulation. The high-frequency pulsating voltage injection method used in the actual mining electric locomotive control system,through field test and subsequent operation proved its accuracy and feasibility.%永磁同步电机作为矿用电机车的牵引电机，在进行控制时，准确获得其转子位置信息至关重要。将高频电压信号注入电机，利用龙贝格观测器估计转子角度和转速，实现了永磁同步电机的无传感器控制，并通过仿真进行验证。将高频脉振电压注入法运用于实际的矿用电机车的控制系统，通过现场试验和后期运行证明了其准确性和可行性。
