Optimized LADRC for Sub-Synchronous Oscillation Suppression in Wind Turbines

Applied Sciences
Sub-synchronous oscillation problems may be induced when direct-drive wind turbines are connected to a weak AC power grid, and then it is necessary to analyze the mechanism of sub-synchronous oscillation and study effective suppression methods.

Linear active disturbance rejection control of the hovercraft vessel model [PDF]

Ocean Engineering, 2015
A linearizing robust dynamic output feedback control scheme is proposed for earth coordinate position variables trajectory tracking tasks in a hovercraft vessel model. The controller design is carried out using only position and orientation measurements. A highly simplified model obtained from flatness considerations is proposed which vastly simplifies
