【Abstract】 This paper studies the problem of robust control for a class of uncertainty singular systems with time delay and disturbance both in state and input,and disturbance in output.By means of Riccati equation approach,a sufficient condition is obtained for a singular system by using Riccati equation approach and choosing an appropriate Lyapunov function.For such controller is derived in terms of the solutions of Riccati equations.For all admissible uncertainties,the closed-loop system is robustly asymptotically stable and satisfies a prescribed performance.更多还原
