增广的降维观测器 augmented reduced order observer
For the fast subsystem, an observer-based state-feedback control method is proposed. A reduced-order observer is proposed to estimate the corrected flexible mode variables that can not be measured directly.
最后,针对快变子系统,提出了一种基于观测器的状态反馈控制方法,设计了降维观测器估计不可测状态,即柔性模态偏差,然后基于重构的系统状态,设计了LQR控制器抑制快变子系统的弹性振动。
