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 ...
Enhanced 2-DOF PID Controller Tuning Based on an Uncertainty and Disturbance Estimator With Experimental Validation

Balaguer Garín, Vicente; González Sorribes, Antonio; García Gil, Pedro José; Blanes Noguera, Francisco (Institute of Electrical and Electronics Engineers, 2021)

[EN] In this paper a novel tuning procedure for Two-Degree-of-Freedom (2-DOF) PID controllers is proposed. The tuning methodology is based on an Uncertainty and Disturbance Estimator. As a result, an equivalent 2-DOF PID ...
Hierarchical Triple-Maglev Dual-Rate Control Over a Profibus-DP Network

Pizá, Ricardo; Salt Llobregat, Julián José; Sala, Antonio; Cuenca Lacruz, Ángel Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2014-01)

This paper addresses a networked control system application on an unstable triple-magnetic-levitation setup. A hierarchical dual-rate control using a Profibus-decentralized peripherals network has been used to stabilize ...
Novel Strategies to design Controllers and State Predictors based on Disturbance Observers

Castillo Frasquet, Alberto (Universitat Politècnica de València, 2021-03-30)

[ES] Los sistemas de ingeniería o físicos suelen ser inciertos. Su incertidumbre se manifiesta cuando el sistema muestra comportamientos que son relativamente diferentes a los que su modelo predice; estando principalmente ...
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 ...
Rejection of mismatched disturbances for systems with input delay via a predictive extended state observer

Sanz Diaz, Ricardo; García Gil, Pedro José; Fridman, Emilia; Albertos Pérez, Pedro (John Wiley & Sons, 2018-04-01)

[EN] The problem of output stabilization and disturbance rejection for input-delayed systems is tackled in this work. First, a suitable transformation is introduced to translate mismatched disturbances into an equivalent ...
Robust controller design for input-delayed systems using predictive feedback and an uncertainty estimator

Sanz Diaz, Ricardo; García Gil, Pedro José; Albertos Pérez, Pedro; Zhong, Qing-Chang (John Wiley & Sons, 2017-07-10)

[EN] This paper deals with the problem of stabilizing a class of input-delayed systems with (possibly) nonlinear uncertainties by using explicit delay compensation. It is well known that plain predictive schemes lack ...
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 ...
Value Function Estimation in Optimal Control via Takagi-Sugeno Models and Linear Programming

Díaz Iza, Henry Paúl (Universitat Politècnica de València, 2020-03-23)

[ES] La presente Tesis emplea técnicas de programación dinámica y aprendizaje por refuerzo para el control de sistemas no lineales en espacios discretos y continuos. Inicialmente se realiza una revisión de los conceptos ...
