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 ...
Operating Point Optimization of a Hydrogen Fueled Hybrid Solid Oxide Fuel Cell-Steam Turbine (SOFC-ST) Plant
Ugartemendia de la Iglesia, Juan José ; Ostolaza Zamora, Joseba Xabier ; Zubia Olaskoaga, Itziar (MDPI, 2013-09-30)

; ; Ugartemendia de la Iglesia, Juan José ; (MDPI, 2014-07)
The aim of this research study has been to design a gain scheduling (GS) digital controller in order to control the voltage of an islanded microgrid in the presence of fast varying loads (FVLs), and to compare it to a ...
Microtab design and implementation on a 5MW wind turbine
; ; Boyano Murillo, Ana Isabel ; ; López Guede, José Manuel (MDPI, 2017-05-24)
; ; López Guede, José Manuel (MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
