H ∞ Control and Exponential Stability of Nonlinear Nonautonomous Systems with Time-Varying Delay

摘要: This paper addresses the design of H ∞ state feedback controllers for a class nonlinear time-varying delay systems. The interesting features here are that system in consideration is nonautonomous with fast-varying delays, also involved observation output, and to be designed satisfy some exponential stability constraints on closed-loop poles. By using proposed Lyapunov functional approach, neither controllability assumption nor bound restriction perturbations required obtain new sufficient conditions control. derived terms solution standard Riccati differential equations, which allows simultaneous computation two bounds characterize rate solution.
