Pressure Drops and Energy Consumption Model of Low-Scale Closed Circuit Cooling Towers
(MDPI, 2021)
Heat transfer models of closed-circuit cooling towers are available in the literature. Using these models, traditional parametric studies show how the inlet conditions of the streams influence the cooling capacity. This ...
Study of Sound Perception Evaluation in Refrigeration Gases
(MDPI, 2023)
In the past, sound design was focused on the minimization of the emitted sound, understanding that the lower the sound, the better. Nowadays, this concept is outdated; in addition to the sound pressure level, many more ...
Adaptive Pitch Controller of a Large-Scale Wind Turbine Using Multi-Objective Optimization
(MDPI, 2021)
This paper deals with the control problems of a wind turbine working in its nominal zone. In this region, the wind turbine speed is controlled by means of the pitch angle, which keeps the nominal power constant against ...
A hybrid modeling approach for steady-state optimal operation of vapor compression refrigeration cycles
(2018)
This paper presents a steady-state hybrid modeling approach for vapor compression refrigeration cycles which is intended to achieve an optimal system operation from an energy consumption point of view. The model development ...
Interactive Tuning Tool of Proportional-Integral Controllers for First Order Plus Time Delay Processes
(MDPI, 2018)
Engineering education and, particularly, control engineering, has shown growth in research and development activities during last years. Currently, proportional–integral (PI) and proportional–integral–derivative (PID) ...
Interactive Tool for Frequency Domain Tuning of PID Controllers
(MDPI, 2018)
This paper presents an interactive tool focused on the study of
proportional-integral-derivative (PID) controllers. Nowadays, PID control loops are extensively used
in industrial applications. However, it is reported ...
Experiencia de trabajo en equipo: diseño y control de un sistema multivariable de depósitos interconectados
(UCOPress, 2019)
En este trabajo se presenta una experiencia de trabajo en grupo que pretende mejorar tanto competencias generales (organización, planificación, resolución de problemas, toma de decisiones, etc.) como específicas (modelado, ...
Iterative Method for Tuning Multiloop PID Controllers Based on Single Loop Robustness Specifications in the Frequency Domain
(MDPI, 2021)
Multiloop proportional-integral-derivative (PID) controllers are widely used for controlling multivariable processes due to their understandability, simplicity and other practical advantages. The main difficulty of the ...
Multivariable PID control by decoupling
(2016)
This paper presents a new methodology to design multivariable PID controllers based on decoupling control. The method is presented for general n×n processes. In the design procedure, an ideal decoupling control with integral ...
Object oriented modelling and simulation of hydropower plants with run-of-river scheme: A new simulation tool
(2009)
This paper presents the design of a component library for modelling hydropower plants, and describes the development of a new simulation tool for small hydropower plants with a run-of-river scheme. After reviewing the ...
