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 ... -
Multivariable PID control by decoupling
Vázquez Serrano, Francisco J.; Morilla, Fernando; Garrido, J. (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 ... -

Optimization with genetic algorithms of individual pitch control design with and without azimuth offset for wind turbines in the full load region
Lara, Manuel; Garrido, J.; Van Wingerden, Jan Willem; Mulders, Sebastian Paul; Vázquez Serrano, Francisco J. (Elsevier, 2023)The reduction of fatigue loadings in wind turbines to increase their lifetime has become of special interest from a control viewpoint. Individual Pitch Control (IPC) is a well-known approach used to mainly mitigate periodic ... -
Practical advantages of inverted decoupling
Vázquez Serrano, Francisco J.; Morilla, Fernando; Hägglund, T.; Garrido, J. (2011)This paper presents a study of the main advantages of inverted decoupling in 2x2 processes. Two simulation examples and an experimental process are used to show these advantages in comparison with simplified decoupling. ... -
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 ... -
