Research on Speed Sensorless Control of Long Stator Linear Synchronous Motor Based on EEMF
摘要
Abstract
Motion control of synchronous motors requires accurate position and velocity signalsto realize field orientation.When long stator linear synchronous motor runs at high speed,the position and velocity signalsis hard to be obtained by mechanical sensor.To solve this problem,a speed sensorless control method based on extended electromotive force (EEMF) is studied forlong stator linear synchronous motor.With the mathematical model of long stator linear synchronous motor,the robustness of speed sensorless control methodbased on EEMFisanalyzed.Simulation and experimental results show that the speedsensorless of EEMF with phase-lock loop (PLL) achieve closed-loop control for the long stator linear synchronous motor at high speed,and this method is robustto the motorparameters.关键词
