LMI-based H-infinity control scheme for constrained systems and its moving horizon implementation
基于LMI的约束系统H∞控制及其滚动优化实现

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.
