摘要
介绍了一种无速度传感器的四极电磁悬浮系统控制方法。采用电流作为观测器的输入,通过观测器得到气隙位置等状态量。系统中加入干抗力观测器,提高了抗干扰力的能力。该系统不使用位置传感器,可以简化结构,节约成本。
A control method for 4-pole electromagnetic suspension system sensorless was proposed. Current was the input of observer, and gap position can be got from observer. The control system added anti-interrupt observer, which could improve the anti-interrupt ability. The control system sensorless was simple and cheap.
