摘要
通常永磁同步直线电机(PMLSM)的闭环控制需要使用传感器来获取电流的反馈值以及电角度,然而采用机械式传感器不仅会增加控制系统的复杂度,还会增加设计成本。对此,给出PMLSM自动门无位置传感器控制系统的硬软件解决方案。
Traditionally,the closed-loop control of PMLSM requires the use of sensors to obtain the feedback value of the current and the electrical angle.However,the use of mechanical sensors not only increases the complexity of the control system,but also increases the design cost.This paper presents the software and hardware solutions of sensorless control system of permanent magnet synchronous linear motor automatic door.
