Delay-Dependent Robust Finite-Time H_∞ Control for Uncertain Large Delay Systems Based on a Switching Method

摘要

The robust finite-time H-infinity control for a kind of uncertain delay systems with large delay period (LDP) is discussed in this paper. First, a switching technique is exploited to transform the original system into a switched delay system. Second, within the limitation of frequency and length rate of LDP, a state feedback controller is designed to guarantee that the closed-loop system is robust finite-time bounded. Third, the finite-time H-infinity performance analysis for the closed-loop system is developed. Finally, two examples are presented to clarify the validity of the proposed approach.
