| 摘 要： | 以刚体的平动和转动为状态构造主动磁轴承(AMB) 转子控制系统模型,可以清晰反映控制力矩(CMG) 陀螺效应的影响。利用此模型,着重分析了目前常用的分散控制和分散加交叉控制方式下转子的后向涡动特征,并提出模态解耦控制的概念,指出此控制律可以根除转子的后向涡动,且具有最佳的稳定性。

| Abstract: | The model of AMB rotor control system in industry can not manifest the gyro effect in CMG, so that it is inconvenient to design the control law against the rotor vortex. A system moeel based on the rotor translation and rotation is introduced, and the gyro effect is clearly reflected. The backward vortex under different methods of AMB control including the decentralized control and cross-feedback control are analysed. The concept of Modal Decouple Control is put forward, and the backward vortex of rotor can be diminished at original offset situation and better stability is achieved under this control law. |
