Robust stabilization of time-delay discrete switched affine systems via a predictive switching control law

Gerson Portilla, Carolina Albea, Alexandre Seuret

This paper addresses the robust control of uncertain discrete-time switched affine systems subject to a single unitary input delay. The unique feature of this class of systems lies…

Robust predictive control design for uncertain discrete switched affine systems subject to an input delay

Gerson Portilla, Carolina Albea, Alexandre Seuret

Robust stabilization conditions for uncertain switched affine systems subject to a unitary input delay are presented. They are obtained through the Lyapunov framework and a min-swi…

A Switching Strategy for Event-Trigger Control of Spacecraft Rendezvous

Tommaso Del Carro, Gerson Portilla, Alexandre Seuret +1

This paper presents the design of a state-feedback control law for spacecraft rendezvous, formulated using the Hill-Clohessy-Wiltshire equations. The proposed method introduces an…

Lyapunov-Krasovskii functionals for some classes of nonlinear time delay systems

Gerson Portilla, Irina V. Alexandrova, Sabine Mondié

In this contribution, we study an homogeneous class of nonlinear time delay systems with time-varying perturbations. Using the Lyapunov-Krasovskii approach, we introduce a function…

Estimates for weighted homogeneous delay systems: A Lyapunov-Krasovskii-Razumikhin approach

Gerson Portilla, Irina Alexandrova, Sabine Mondié

In this paper, we present estimates for solutions and for the attraction domain of the trivial solution for systems with delayed and nonlinear weighted homogeneous right-hand side…

Estimates for solutions of homogeneous time-delay systems: Comparison of Lyapunov-Krasovskii and Lyapunov-Razumikhin techniques

Gerson Portilla, Irina Alexandrova, Sabine Mondié +1

In this contribution, the estimates for the response of time delay systems with nonlinear homogeneous right-hand side of degree strictly greater than one are constructed. The exist…
