| 中文摘要 |
| 在LMI优化框架下,讨论有时域硬约束线性系统的H∞控制问题.首先提出了一种基于LMI优化的状态反馈方法,并给出了闭环系统保证H∞性能和满足时域硬约束的条件.在此基础上,融合预测控制的滚动优化原理讨论了一种滚动时域H∞性能控制方法.通过对H∞性能指标γ的在线最小化,闭环系统能实时协调控制性能要求和硬约束,并充分利用有限的控制能力提高控制性能. |
| 英文摘要 |
| In the framework of LMI(Linear Matrix Inequality) optimization,this paper addresses the H-infinity control problem for linear systems with time-domain hard constraints.An LMI-based state-feedback solution is presented and conditions for guaranteeing closed-loop H-infinity performance and satisfying the time-domain constraints are given.Combining the moving horizon principle of model predictive control,a moving horizon H-infinity performance control scheme is discussed.By minimizing the H-infinity performance index on-line,the closed-loop system is able to manage the trade-off between required high performance and satisfying hard constraints,and to enable the most of the limited control to achieve good performance. |
