本文提出了一种新的建模方法和控制系统的设计过程中的柔性转子具有多弹性模态的主动磁轴承。本研究的目的是使转子旋转通过由柔性模态引起的临界转速。为了实现这一点，有必要同时控制柔性转子的运动和振动。提出了一种新的建模方法--扩展降阶物理模型，统一表达了其运动和振动。利用该模型设计了悬浮转子的PID控制器和抑制转子振动的LQ控制器。
This paper presents a new modeling method and a control system design procedure for a flexible rotor with many elastic modes by using active magnetic bearings. The purpose of our research is to rotate the rotor for passing through critical speeds caused by flexible modes. To achieve this, it is necessary to control motion and vibration of the flexible rotor simultaneously. The new modeling method named as Extended Reduced Order Physical Model is presented to express its motion and vibration uniformly. By using this model, a PID controller to levitate the rotor and a LQ controller to suppress its vibration are designed.
