The guaranteed cost control problem via the decentralized robust control for nonlinear uncertain large-scale systems that have delay in both state and control input is considered. Sufficient conditions for the existence of guaranteed cost controllers are given in terms of linear matrix inequality (LMI). It is shown that the decentralized local state feedback controllers can be obtained by solvi...

This paper considers the guaranteed cost control problem for a class of two-dimensional (2-D) uncertain discrete systems described by the Fornasini-Marchesini (FM) first model with norm-bounded uncertainties. New linear matrix inequality (LMI) based characterizations are presented for the existence of static-state feedback guaranteed cost controller which guarantees not only the asymptotic stab...

Abstract. This paper deals with the problem of guaranteed cost control for a class of uncertain nonlinear time-delay systems. A new memory hybrid guaranteed cost controller is adopted to make the resulting closed-loop system asymptotically stable and cost function have a lower upper bound. The closed-loop system with such memory hybrid guaranteed cost controller can be regarded as a switched sy...

This article concerns the delay-independent guaranteed-cost control problem via memoryless state feedback for a class of neutral-type systems with structural uncertainty and a given quadratic cost function. New delay-independent conditions for the existence of the guaranteed-cost controller are presented in the term of LMIs. An algorithm involving optimization is proposed to design a controller...

This paper discusses the design and implementation of H2 guaranteed cost control for dual-stage hard disk drive trackfollowing servo systems. The proposed approach is based on H2 guaranteed cost analysis, in which an upper bound on the worst-case H2 performance of a discrete-time system with gainbounded unstructured uncertainty is determined via several Riccati equations. Subsequently, the outp...

This paper discusses the reliable guaranteed cost control problem of networked control systems with timevarying sampling period and actuator failures for a given quadratic cost function. For linear time-invariant controlled plant, we assume that the time delay is constant and shorter than the sampling period, the sampling is time-varying within a certain known bound, the system is transformed i...

In this paper, the problem of nonfragile reliable guaranteed cost control for networked control systems with time-varying sampling period sensors and actuator failures is concerned for a given quadratic cost function. For linear time-invariant controlled plant, under the assumption that the sampling period is time-varying within a certain known bound, the time delay is constant and shorter than...
