摘要
针对陀螺效应,传感器和径向磁轴承的非共点安装以及轴颈倾斜等因素引起的径向磁轴承间的耦合,本文建立一个考虑径向四自由度耦合的多输入多输出系统,并在此基础上,推导出状态空间的表达式,给出了线性二次型最优控制的仿真分析。
The coupling between the magnetic bearings is caused by the gyroscopic effect. This paper introduces a MIMO system considering the radial four-degree-of-freedom coupling,and a state-space model is established. A state feedback law is designed based on the Linear Quadratic theory.
