[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.
