Publicación Machine Learning Weather Soft-Sensor for Advanced Control ofWastewater Treatment Plants(MDPI, 2019) Hernández del Olmo, Félix; Gaudioso Vázquez, Elena; Duro Carralero, Natividad; Dormido Canto, RaquelControl of wastewater treatment plants (WWTPs) is challenging not only because of their high nonlinearity but also because of important external perturbations. One the most relevant of these perturbations is weather. In fact, different weather conditions imply different inflow rates and substance (e.g., N-ammonia, which is among the most important) concentrations. Therefore, weather has traditionally been an important signal that operators take into account to tune WWTP control systems. This signal cannot be directly measured with traditional physical sensors. Nevertheless, machine learning-based soft-sensors can be used to predict non-observable measures by means of available data. In this paper, we present novel research about a new soft-sensor that predicts the current weather signal. This weather prediction differs from traditional weather forecasting since this soft-sensor predicts the weather conditions as an operator does when controling the WWTP. This prediction uses a model based on past WWTP influent states measured by only a few physical and widely applied sensors. The results are encouraging, as we obtained a good accuracy level for a relevant and very useful signal when applied to advanced WWTP control systems.Publicación DESARROLLO DE UNA APLICACIÓN PARA LA INTEGRACIÓN DE TÉCNICAS DE RECONOCIMIENTO DE PATRONES(XXVI Jornadas de Automática, 2005, Alicante-Elche, ISBN: 84-689-0730-8, 2005-01-01) Farias Castro, Gonzalo Alberto; Santos, Matilde; Dormido Canto, RaquelPublicación Comparison of H∞ with QFT applied to an Altitude Command Tracker for an UAV(European Control Conference 2007, July 2-5, 2007, Kos, Greece, 2007-11-29) López, J.; Gómez, J.

However, their performance is far from optimal due to the high non-linearity of the biological and changing processes involved. Therefore, more advanced control techniques are proposed in the literature (e.g., using artificial intelligence techniques). However, these new control techniques have not been compared to the traditional approaches that are actually being used in real plants. To this end, in this paper, we present a comparison of the PID control configurations currently applied to control the dissolved oxygen concentration (in the active sludge process) against a reinforcement learning agent. Our results show that it is possible to have a very competitive operating cost budget when these innovative techniques are applied.Publicación The Three-Tank System: A Remote and Virtual Control Laboratory using Easy Java Simulations(2005-01-01) Vargas Oyarzun, Héctor; Dormido Bencomo, Sebastián; Duro Carralero, Natividad; Dormido Canto, Raquel; Sánchez Moreno, José; Pastor Vargas, Rafael; Dormido Canto, SebastiánPublicación Aplicación de un sistema de medición automática en prácticas de respuesta en frecuencia(1998-01-01) Lázaro Obensa, Juan Carlos; Morilla García, Fernando; Hernández Berlinches, Roberto; Dormido Canto, RaquelPublicación Easy Java Simulations: an Open-Source Tool to Develop Interactive Virtual Laboratories Using MATLAB/Simulink(TEMPUS Publications, The International Journal of Engineering Education: Especial issue on Matlab/Simulink in engineering education, 21, 5, 798-813, 2005, 2005-01-01) Esquembre Martínez, Francisco; Dormido Bencomo, Sebastián; Sánchez Moreno, José; Martín Villalba, Carla; Dormido Canto, Sebastián; Dormido Canto, Raquel; Pastor Vargas, Rafael; Urquía Moraleda, AlfonsoPublicación WEB-BASED LEARNING RESOURCES FOR VOCATIONAL TRAINING FOR AUTOMATION TECHNICIANS(IFAC 2006, 2006-01-01) Vargas Oyarzun, Héctor; Dormido Bencomo, Sebastián; Farias Castro, Gonzalo Alberto; Esquembre Martínez, Francisco; Sánchez Moreno, José; Duro Carralero, Natividad; Dormido Canto, Raquel; Dormido Canto, Sebastián
