Tuning and robustness analysis of event-based PID controllers under different event generation strategies
(Taylor & Francis, 2017-05)
In this article, we propose practical rules for tuning event-based PID controllers with two sampling strategies: symmetric send-on-delta (SSOD) and regular quantification (RQ). We present a detailed analysis about the ...
State estimator for multisensor systems with irregular sampling and time-varying delays
(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 ...

A new methodology for facilitating the design of safety-related parts of control systems in machines according to ISO 13849:2006 standard
(Elsevier, 2018)
Safety is a fundamental requirement of production systems considered throughout all the stages of a machine’s lifecycle. Due to its importance to avoid accidents and injuries, safety specifications have been explicitly ...
A simplified black-box model oriented to chilled water temperature control in a variable speed vapour compression system
(Elsevier, 2011-02)
The aim of this work is to propose a black-box model to accurately predict the chilled water temperature dynamic response of a vapour compression chiller. The model is oriented to be of value in determining an adequate ...
Improved efficiency in sensitivity calculations for bioreactor models
(Elsevier, 2009)
Sensitivity functions are a basic tool in the parametric identification of models. They can be used to obtain the gradient needed by optimization algorithms in the estimation of parameters and to calculate the Fisher ...
Tuning procedure for event-based PI controllers under regular quantization with hysteresis
(Elsevier, 2021-04-20)
In this paper a tuning procedure is proposed for event based PI controllers with Regular Quantization with Hysteresis (RQH) sampling law. The RQH is a generalization of Symmetric Send on Delta (SSOD) strategy which decreases ...
Tuning PID controllers with Symmetric Send-on-Delta sampling strategy
(Elsevier, 2019-10-23)
A procedure for tuning PID controllers with SSOD sampling for FOPTD systems is proposed. It is based on the definition of a new robustness measure to avoid limit cycle oscillations, called the Tsypkin margin (MT). This ...
