Reliable Guaranteed Cost Control for Uncertain Discrete Time-Delay Systems with Actuator Failures
The reliable guaranteed cost control problem is discussed in this paper for a class of uncertain discrete time-delay systems with actuator failures. The considered system is assumed to have generalized matched parameter uncertainties. The model of actuator failures is more general and practical. By using Lyapunov stability theory, the sufficient condition for the existence of memoryless state feedback reliable guaranteed cost controllers is presented in terms of a linear matrix inequality (LMI). Then the resulting closedloop system is asymptotic stable and the closed-loop cost function value is not more than a specified upper bound for any admissible uncertainties. Furthermore, a convex optimization problem with LMI constraints is formulated to design the optimal reliable guaranteed cost controller which minimizes the upper bound of the closed-loop cost function. A simulation example demonstrates the effectiveness of the design method.
