挠性系统的鲁棒控制设计

Robust control design for flexible systems

提出一种新的鲁棒设计思想 :将挠性模态部分的 Nyquist图线安排到右半平面。由于综合运用了频域分析、极点配置、正实性引理、线性矩阵不等式等概念和算法 ,使得这种鲁棒控制设计得以实现 ,且简单直观。

A new design strategy is presented to place the locus part of the flexible mode on the right-half Nyquist plane. This design goal is achieved by integrating various concepts and algorithms in control theory, including the frequency domain analysis, the pole placement, the Positive-Real Lemma and LMI's. The design method is simple and intuitive. Examples illustrate the validity of the design method.
