【摘要】：針對長定子直線同步電機高速運行時,機械傳感器無法準確地獲得轉子位置和速度信號的問題,研究了一種適合在長定子直線同步電機中應用的擴展反電動勢法無速度傳感器控制策略�；陂L定子直線同步電機的數學模型,分析了擴展反電動勢法用于長定子直線同步電機無速度傳感器控制的魯棒性。仿真和實驗結果證明了基于鎖相環(huán)的擴展反電動勢法無速度傳感器控制能夠實現高速時電機的無速度傳感器閉環(huán)控制,并且此方法對電機參數變化具有較強的魯棒性。
[Abstract]:In order to solve the problem of high-speed operation of the long-stator linear synchronous motor, the problem of the rotor position and speed signal can not be accurately obtained by the mechanical sensor, and the control strategy of the extended back-EMF method suitable for the long-stator linear synchronous motor is studied. Based on the mathematical model of long-stator linear synchronous motor, the robustness of the extended back-EMF method for sensorless control of long-stator linear synchronous motor is analyzed. The simulation and experimental results show that the non-speed sensor control based on the extended back-EMF method of the phase-locked loop can realize the closed-loop control of the speed-free sensor of the motor at high speed, and the method has strong robustness to the change of the parameters of the motor.
