The problem of delay-dependent robust H∞ control for uncertain singular systems with discrete and distributed delays is revisited in this paper. The parameter uncertainties are assumed to be norm-bounded and the time delays to be time-varying, size-bounded and derivative-bounded. Using Lyapunov-Krasovskii functional and free weighting matrix methods, a new delay-dependent bounded real lemma is presented...
In this paper, the concept of H∞ control for discrete-time systems is extended over a finite-time interval, we discuss the finite-time control H∞ problem for discrete-time linear system with time-varying norm-bounded exogenous disturbance, the main aim is to design a state feedback controller which guarantees that the closed-loop system is finite-time boundedness and reduces the effect of the disturbance...
The problem of guaranteed cost robust Hinf reliable control is investigated for time-varying delay uncertain systems against actuator failures. In the considered system, the time-varying delay and its derivative are bounded. Actuators are classified into two sets (One set is susceptible to failure and the other set is not susceptible to failure). All the outputs of the failure actuators are assumed...
The Hinfin control problem is studied in this paper for networked control systems (NCSs) with short time-varying delays. By considering state feedback controllers, the closed-loop NCS is described as a discrete-time linear uncertain system model, and the uncertain part reflects the effect of the variation nature of the network-induced delays on the system dynamics. Then, a sufficient condition is...
This paper focuses on the asymptotic stability and the state feedback control for T-S fuzzy systems with a time-varying delay by employing an improved free-weighting matrix approach. By taking the relationship among the time-varying delay, its upper bound and their difference into account, a new less conservative delay-dependent stability criteria are obtained without ignoring any useful terms in...
This paper deals with the problem of controller failure analysis for T-S fuzzy systems with time-varying delay. The T-S fuzzy systems can be stabilized by a pre-designed state feedback controller. Our objective is to establish conditions concerning controller failure time and frequency, under which the systems still keep exponentially stable. Based on piecewise Lyapunov functional method, exponential...
