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 ...
Comparative Analysis of Decoupling Control Methodologies and H¥ Multivariable Robust Control for Variable-Speed, Variable-PitchWind Turbines: Application to a Lab-Scale Wind Turbine
(MDPI, 2017)
This work is focused on the improvement of variable-speed variable-pitch wind turbine
performance by means of its control structure. This kind of systems can be considered as multivariable
nonlinear processes subjected ...
Centralized multivariable control by simplified decoupling
(2012)
This paper presents a generalized formulation of simplified decoupling to n×n processes that allows for different configurations depending on the decoupler elements set to unity. To apply this decoupling method, the ...
Centralized Inverted Decoupling Control
(2013)
This paper presents a new methodology of multivariable centralized control based on the structure of inverted decoupling. The method is presented for general n×n processes, obtaining very simple general expressions for the ...
Educational software tool for decoupling control in wind turbines applied to a lab‐scale system
(2018)
This paper presents an educational software tool, called wtControlGUI, whose main purpose is to show the applicability and performance of different decoupling control strategies in wind turbines. Nowadays wind turbines are ...
Comparative analysis of decoupling control methodologies and H∞ multivariable robust control for VS-VP wind turbines
(IEEE, 2015)
Wind turbines systems considered multivariable processes can work in several operational modes. Each mode can be represented with a dynamic model. This fact supposes a difficulty in controlling these types of systems. In ...
