Pitch Control of Three Bladed Large Wind Energy Converters—A Review

open access: yesEnergies, 2021
Modern multi-megawatt wind turbines are currently designed as pitch-regulated machines, i.e., machines that use the rotation of the blades (pitching) in order to adjust the aerodynamic torque, such that the power is maintained constantly throughout a ...

Application of velocity-based gain-scheduling to lateral auto-pilot design for an agile missile [PDF]

open access: yes, 2001
In this paper a modern gain-scheduling methodology is proposed which exploits recently developed velocity-based techniques to resolve many of the deficiencies of classical gain-scheduling approaches (restriction to near equilibrium operation, to slow ...

On distributed scheduling in wireless networks exploiting broadcast and network coding [PDF]

open access: yes, 2010
In this paper, we consider cross-layer optimization in wireless networks with wireless broadcast advantage, focusing on the problem of distributed scheduling of broadcast links. The wireless broadcast advantage is most useful in multicast scenarios.
