Observer-based controllers with data dropout rate adaptation
Dolz Algaba, Daniel; Peñarrocha-Alós, Ignacio; Sanchis LLopis, Roberto Wiley (2017-02)In this work, we address the observer-based control problem for networked control systems with an unknown time-varying packet arrival rate (PAR) and under root mean square-norm bounded disturbances. We assume packetized ... -
Optimal tuning of PID controllers with derivative filter for stable processes using three points from the step response
Sanchis LLopis, Roberto; Peñarrocha-Alós, Ignacio ISA Transactions (2023)This paper proposes a novel approach for tuning Proportional Integral Derivative (PID) controllers, utilizing experimental data obtained from an open-loop step input. We propose to use the measurements of the times taken ... -
Performance Tradeoffs for Networked Jump Observer-Based Fault Diagnosis
Dolz Algaba, Daniel; Peñarrocha-Alós, Ignacio; Sanchis LLopis, Roberto Institute of Electrical and Electronics Engineers (IEEE) (2015-04)Print Request Permissions In this paper, we address the fault diagnosis problem for discrete-time multi-sensor systems over communication networks with measurement dropouts. We use the measurement outcomes to model the ... -
Performance, robustness and noise amplification trade-offs in Disturbance Observer Control design
Tena, David; Peñarrocha-Alós, Ignacio; Sanchis LLopis, Roberto Elsevier (2022-03-11)In this work, we propose a Disturbance Observer (DOB) with a low pass filter with a single tuning parameter. The DOB can be added to a standard PI controller that is assumed to be controlling the system. Our DOB design can ... -
Performance-based design of PI observers for fault diagnosis in LTI systems under Gaussian noises
Sales-Setién, Ester; Peñarrocha-Alós, Ignacio; Dolz Algaba, Daniel; Sanchis LLopis, Roberto IEEE (2016)This work addresses the fault diagnosis problem for LTI systems under the presence of Gaussian noises through model-based proportional-integral observers with predefined gains. We propose an integrated design of residual ... -
PI and PID auto-tuning procedure based on simplified single parameter optimization
Romero Pérez, Julio Ariel; Sanchis LLopis, Roberto; Balaguer, Pedro Elsevier (2011)In this paper a new auto-tuning algorithm for PI and PID controllers based on relay experiments is proposed to minimize the load disturbance integral error (IE) by maximizing the integral gain, subject to a desired phase ... -

State estimator for multisensor systems with irregular sampling and time-varying delays
Peñarrocha-Alós, Ignacio; Romero Pérez, Julio Ariel; Sanchis LLopis, Roberto Taylor & Francis (2012)This article addresses the state estimation in linear time-varying systems with several sensors with different availability, randomly sampled in time and whose measurements have a time-varying delay. The approach is based ... -
Synthesis of nonlinear controller for wind turbines stability when providing grid support
Peñarrocha-Alós, Ignacio; Dolz Algaba, Daniel; Aparicio, N.; Sanchis LLopis, Roberto John Wiley & Sons, Ltd. (2013)This paper presents a new nonlinear polynomial controller for wind turbines that assures stability and maximizes the energy produced while imposing a bound in the generated power derivative in normal operation (guarantees ... -
