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 ...
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

Optimal Active Generator Torque Control Strategies for Tower Lateral Load Reduction in the IEA 15 MW Wind Turbine
(EUROSIM, 2023)
The extension of wind turbines' lifetime by reducing fatigue loads is a topic of interest. The contribution of this work is focused on designing a controller that mitigates lateral tower vibrations in the full load region. ...
Inverted decoupling internal model control for square stable multivariable time delay systems
(2016-09-06)
This paper presents a new tuning methodology of the main controller of an internal model control structure for n×n stable multivariable processes with multiple time delays based on the centralized inverted decoupling ...
Practical advantages of inverted decoupling
(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. ...
