摘要
考虑不确定离散广义系统的鲁棒 H∞ 控制问题 ,目的是设计状态反馈控制律 ,使得对所有容许的不确定参数 ,闭环系统正则、因果、稳定且满足给定的 H∞ 性能指标 ,本文给出了鲁棒 H∞ 状态反馈控制律的存在条件及其代数表达式 .
In this paper,the problem of robust H ∞ control for uncertain discrete singular systems is considered.The parameter uncertainty is assumed to be time invariant entering both the state and input matrices.The problem we address is to design state feedback controllers such that the resulting closed loop system is regular,causal,stable as well as satisfying a prescribed H ∞ norm bound constraint for all admissible uncertainties.The conditions for the existence of desired state feedback controllers are given and the algebraic expression of expected controllers is proposed.
