摘　　要：研究了基于Delta算子描述的区间系统鲁棒H∞ 镇定设计问题。在给出了区间系统的一种等价描述后 ,利用H∞ 控制的思想 ,将系统的鲁棒镇定设计问题化为求解Riccati不等式。所设计的控制器可使闭环系统鲁棒稳定 ,而且对可允许的参数变化具有一定的H∞ 性能。Robust H ∞ control in interval delta opera tor systems is studied. Based on a kind of equivalent presentation of t he interval systems, some s ufficient conditions for robust stabilization of the systems are presented. The state feedback control for robust stabilization can be obtained by solving Ricca ti inequalities, which can stabilize the systems and guarantee a prescribed H ∞ performance on attenuation of all admissible parameter uncertainties. T he approach can unify the related results of the continuous and discrete interva l systems into a delta framework.
