Mejora de la estrategia de muestreo en bucles de control PID basados en eventos
(Área de Ingeniería de Sistemas y Automática, Universidad de Extremadura, 2018-08-05)
En este artículo se presenta un estudio sobre el efecto en la robustez y en la generación de eventos de los diferentes métodos de muestreo empleados en el control basado en eventos, a saber, el muestreo por cuantificación ...
Design of modular and distributable automation software for PLCs
(SCITEPRESS – Science and Technology Publications, 2023-11)
Design and maintainability of modular automation software are common concerns nowadays. Common practice in industry usually overlooks the design phase of software, jumping directly into the coding phase, which typically ...
Implementation and evaluation of event-based PID in the IEC-61499 standard
(IEEE, 2018-08-04)
This paper presents a study about the performance of event-based PID controllers implemented in the standard IEC-61499. The implementation details are addressed and experimental results are given. The main goal is to ...
Quality Indicators for Social Business Intelligence
(IEEE, 2019-10-22)
The main purpose of Social Business Intelligence is to help companies in making decisions by performing multidimensional analysis of the relevant information disseminated on social networks. Although data quality is a ...
A new method for tuning PI controllers with symmetric send-on-delta sampling strategy
(Elsevier, 2016)
In this paper we present a new method for tuning PI controllers with symmetric send-on-delta (SSOD) sampling strategy. First we analyze the conditions that produce oscillations in event based systems considering SSOD ...
Tuning of PID Controllers based on simplified single parameter optimization
(Taylor & Francis, 2010)
A simple method to design PID controllers in the frequency domain based on a simplified constrained optimiza- tion is proposed. The method is based on the use of a single tuning parameter, defined as the quotient between ...
A new approach to averaging level control
(Elsevier, 2011-09)
In this paper, a new simple algorithm for averaging level control is presented. The proposed algorithm is based on the use of a static nonlinear controller to improve the input flow filtering by reducing the slope of the ...
Co-design of H∞ jump observers for event-based measurements over networks
(Taylor & Francis, 2015-07-27)
This work presents a strategy to minimise the network usage and the energy consumption of wireless battery-powered sensors in the observer problem over networks. The sensor nodes implement a periodic send-on-delta approach, ...
PI and PID auto-tuning procedure based on simplified single parameter optimization
(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 ...
