Robust output feedback stabilization for discrete-time systems with time-varying input delay

Finite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay

In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...

Robust ∞ H Control of Switched Uncertain Time-varying Delay Discrete-time Systems via Dynamic Output Feedback

Robust H output feedback control problem for a class of switched linear discrete-time systems possessing normbounded uncertainty and time-varying delay is investigated. A switched dynamic output feedback controller is sought that can robust exponentially stabilize and reduce to a prescribed level the effect of disturbance input on the controlled output in the closed loop. A delay depen dent lin...

Delay-Dependent Robust $mathcal {H}_{infty}$ Output Feedback Control for Uncertain Discrete-Time Switched Systems with Interval Time-Varying Delay

This paper revisits the problem of delaydependent dynamic output feedback control for a class of uncertain discrete-time switched linear state-delayed systems, where the state delay is assumed to be time-varying and of an intervallike type, which means that both the lower and upper bounds of the time-varying delay are available and the parameter uncertainties are assumed to have a structured li...

Stabilization of switched discrete-time systems with time-varying delay

A convex approach is proposed to deal with switched discrete-time systems with time-varying delays. It uses a parameter dependent Lyapunov-Krasovskii functional that allows to assure the robust stability or the robust stabilization of a switched system for arbitrary switching functions. The analysis and the design conditions are formulated as simple feasibility tests of linear matrix inequaliti...
