Control predictor con ponderación de retardos: análisis de prestaciones y robustez ante retardo variable

González, Antonio; Sala, Antonio (Elsevier, 2014-04)

[ES] Los controladores basados en predictor, en particular los obtenidos por métodos de asignación finita de espectro (también conocido como método de reducción), permiten abordar el control por realimentación del estado ...
Estimation in multisensor networked systems with scarce measurements and time varying delays

Albertos Pérez, Pedro (Elsevier, 2012-04)

In this paper, the problem of estimating signals from a dynamic system at regular periods from scarce, delayed and possibly time disordered measurements acquired through a network is addressed. A model based predictor that ...
Gain-Scheduled Predictive Extended State Observer for Time-varying Delays Systems with Mismatched Disturbances

González Sorribes, Antonio; Balaguer Garín, Vicente; García Gil, Pedro José; Cuenca, Ángel (Elsevier, 2019-01)

[EN] In this paper, a novel control scheme for systems with input and output time-varying delays is provided in discrete-time domain. The control strategy combines predictor-like techniques with a delay-dependent gain-scheduled ...
Improved results on stability analysis of time-varying delay systems via delay partitioning method and Finsler's lemma

González Sorribes, Antonio (Elsevier, 2022-09)

[EN] This paper proposes novel conditions based on linear matrix inequalities (LMI) for stability analysis of arbitrarily-fast time-varying delays systems. The time-varying delay interval is divided into smaller pieces in ...
Linear matrix inequalities in multirate control over networks

Cuenca Lacruz, Ángel Miguel; Pizá, Ricardo; Salt Llobregat, Julián José; Sala Piqueras, Antonio (Hindawi Publishing Corporation, 2012)

This paper faces two of the main drawbacks in networked control systems: bandwidth constraints and timevarying delays. The bandwidth limitations are solved by using multirate control techniques. The resultant multirate ...
Optimal Control for Aperiodic Dual-Rate Systems With Time-Varying Delays

Aranda-Escolástico, E.; Salt Llobregat, Julián José; Guinaldo, M.; CHACON, JESUS; DORMIDO, SEBASTIÁN (MDPI AG, 2018-05-09)

[EN] In this work, we consider a dual-rate scenario with slow input and fast output. Our objective is the maximization of the decay rate of the system through the suitable choice of the n-input signals between two measures ...
Output-feedback anti-disturbance predictor-based control for discrete-time systems with time-varying input delays

González Sorribes, Antonio; García Gil, Pedro José (Elsevier, 2021-07)

[EN] This paper investigates the robust stabilization of discrete-time systems with time-varying input delays and model uncertainties by predictor-based anti-disturbance output-feedback control strategies. Here, a novel ...
Robust Predictive Extended State Observer for a Class of Nonlinear Systems with Time-Varying Input Delay

Sanz Diaz, Ricardo; García Gil, Pedro José; Fridman, Emilia; Albertos Pérez, Pedro (Taylor & Francis, 2020-02-01)

[EN] This paper deals with asymptotic stabilisation of a class of nonlinear input-delayed systems via dynamic output feedback in the presence of disturbances. The proposed strategy has the structure of an observer-based ...
Robust stability analysis of filtered Smith predictor for time-varying delay processes

García Gil, Pedro José; González Sorribes, Antonio (Elsevier, 2012)

[EN] This paper focuses on the robust stability analysis ofthe filtered Smith predictor (FSP) dead-time compensator for uncertain processes with time-varying delays. For this purpose, a delay-dependent LMI-based condition ...
Robust stability analysis of formation control in local frames under time-varying delays and actuator faults

González Sorribes, Antonio; Aranda, Miguel; López-Nicolás, Gonzalo; Sagüés, Carlos (Elsevier, 2019-01)

[EN] This paper investigates the robust stability of a multiagent system moving to a desired rigid formation in presence of unknown time-varying communication delays and actuator faults. Each agent uses relative position ...
Robustness of a discrete-time predictor-based controller for time-varying measurement delay

Gonzalez, A.; García Gil, Pedro José; Albertos Pérez, Pedro; Castillo, P; Lozano, R. (International Federation of Automatic Control, 2012-11-01)

A predictor-based controller for time-varying delay systems is presented in this paper and its robustness properties for different uncertainties are analyzed. First, a time-varying delay dependent stability condition is ...
