Adaptive Pitch Controller of a Large-Scale Wind Turbine Using Multi-Objective Optimization
Lara, Manuel; Garrido, J.; Ruz Ruiz, Mario L.; Vázquez Serrano, Francisco J. (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 ... -
Analysis of adaptive individual pitch control schemes for blade fatigue Load reduction on a 15 MW wind turbine
Lara, Manuel; Mulders, Sebastian Paul; Van Wingerden, Jan Willem; Vázquez, Francisco; Garrido, J. (MDPI, 2024)Individual pitch control (IPC) is a method to mitigate periodic blade loads in wind turbines, and it is typically implemented using the multi-blade coordinate (MBC) transform, which converts the blade load measurements ... -
Control multivariable por desacoplo
Morilla, Fernando; Garrido, J.; Vázquez, Francisco (Elsevier, 2013)La interacción entre variables es una característica inherente de los procesos multivariables, que dificulta su operación y el diseño de sus sistemas de control. Bajo el paradigma de Control por desacoplo se agrupan un ... -
Experiencia de trabajo en equipo: diseño y control de un sistema multivariable de depósitos interconectados
Garrido, J.; Ruz Ruiz, Mario L.; Jiménez Hornero, Jorge; Vázquez Serrano, Francisco J. (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, ... -
Improvement of small wind turbine control in the transition region
Ruz Ruiz, Mario L.; Garrido, J.; Fragoso, Sergio; Vázquez, Francisco (MDPI, 2020)Wind energy conversion systems are very challenging from the control system viewpoint. The control difficulties are even more challenging when wind turbines are able to operate at variable speed and variable pitch. The ... -
Interactive Tool for Frequency Domain Tuning of PID Controllers
Garrido, J.; Ruz Ruiz, Mario L.; Morilla, Fernando; Vázquez Serrano, Francisco J. (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 ... -
Interactive Tuning Tool of Proportional-Integral Controllers for First Order Plus Time Delay Processes
Ruz Ruiz, Mario L.; Garrido, J.; Morilla, Fernando; Vázquez Serrano, Francisco J. (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) ... -
Iterative design of centralized PID controllers based on equivalent loop transfer functions and linear programming
Garrido, J.; Ruz, Mario L.; Morilla, Fernando; Vázquez, Francisco (IEEE Access, 2021)This paper deals with the design problem of multivariable Proportional-Integral-Derivative (PID) controllers for square and stable multivariable processes when a linear margin at the Nyquist plot is considered as robustness ... -
Iterative Method for Tuning Multiloop PID Controllers Based on Single Loop Robustness Specifications in the Frequency Domain
Garrido, J.; Ruz Ruiz, Mario; Morilla, Fernando; Vázquez Serrano, Francisco J. (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 ... -
Multi-objective optimization for simultaneously designing active control of tower vibrations and power control in wind turbines
Lara, Manuel; Garrido, J.; Ruz, Mario L.; Vázquez, Francisco (Elsevier, 2023)For wind turbines operating in the full load region, stabilizing the generated power at its nominal value is a key objective. Furthermore, the control of tower vibrations is a major constraint in wind turbine structures ... -
Reflection-aware generation and identification of square marker dictionaries
Garrido-Jurado, Sergio; Garrido, J.; Jurado Rodríguez, David; Vázquez, Francisco; Muñoz-Salinas, Rafael (MDPI, 2022)Square markers are a widespread tool to find correspondences for camera localization because of their robustness, accuracy, and detection speed. Their identification is usually based on a binary encoding that accounts for ... -
Software Tool for Acausal Physical Modelling and Simulation
Jiménez, Jorge E.; Belmonte, Antonio; Garrido, J.; Ruz Ruiz, Mario L.; Vázquez Serrano, Francisco J. (MDPI, 2019)Modelling and simulation are key tools for analysis and design of systems and processes from almost any scientific or engineering discipline. Models of complex systems are typically built on acausal Differential-Algebraic ... -
Stiction compensation for low-cost electric valves
Vázquez, Francisco; Garrido, J.; Ruz, Mario L.; Jiménez, Jorge E. (Elsevier, 2023)Nonlinear dynamics of control valves, such as stiction, can produce significant performance degradation in the control loops where they are involved. There are several works in the literature describing and modelling these ...
