Sliding Mode Control Strategy for Wind Turbine Power Maximization
(MDPI, 2012-07)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a sliding mode control for variable speed wind turbine that incorporates a doubly fed ...
Algorithms for colour image processing based on neurological models
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2011-04-08)
Colour image processing is nowadays mostly achieved through the extrapolation of algorithms
developed for images in grey levels into three colour planes, either RGB or some transformed
planes, such as HSI, CIELAB... These ...
A Real-Time Sliding Mode Control for a Wind Energy System Based on a Doubly Fed Induction Generator
(MDPI, 2014-10)
In this paper, a real time sliding mode control scheme for a variable speed wind turbine that incorporates a doubly feed induction generator is described. In this design, the so-called vector control theory is applied, in ...
A complex systems modelling approach for decentralized simulation of electrical microgrids
(IEEE, 2010)
The structure and behavior of Electrical Grids share many of the properties of Complex Computer Systems, with microgrids and other decentralized electrical systems attached to them, so they can be interpreted as Systems ...
Modeling smart grids as complex systems through the implementation of intelligent hubs
(INSTICC, 2010)
The electrical system is undergoing a profound change of state, which will lead to what is being called the smart grid. The necessity of a complex system approach to cope with ongoing changes is presented: combining a ...
Using the system dynamics paradigm in teaching and learning technological university subjets
(IATED, 2010)
Knowledge of Differential Equations is applied to various scientific fields such as physics, chemistry, biology and engineering and therefore often an important part in the basic subjects of mathematics in the first college ...
Sliding mode position control for real-time control of induction motors
(ICIC International, 2013-07)
A sliding mode position control for high-performance real-time applications of induction motors in developed in this work. The design also incorporates a simple flux estimator in order to avoid the flux sensors. Then, the ...
A Novel Two Stage Controller for a DC-DC Boost Converter to Harvest Maximum Energy from the PV Power Generation
(MDPI, 2020-04-14)
In this article, an efficient and fast two-stage approach for controlling DC-DC boost converter using non linear sliding mode controller for a PV power plant is proposed. The control approach is based on two online methods ...
