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.Abstract: 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.
