Robust H SymboleB@ Control for Singular Time-Delay Systems with Saturating Actuators
Abstract:A method of delay-dependent robust H SymboleB@ control for singular systems with saturating actuators and parameter uncertainties was studied, and both the state and the control input have time delays. Also the influence of the saturating actuator on the input and input delay was studied. A sufficient condition was established by constructing the generalized Lyapunov-Krasovskii function. Based on linear matrix inequality(LMI) approach and singular value theory, a state feedback controller was designed, which guarantees that the resultant closed-loop system is regular, impulse free, and stable with an H SymboleB@ norm bound constraint. Numerical examples show that the proposed methods are less conservative than the existing ones.
