Data-driven repetitive control: Wind tunnel experiments under turbulent conditions

A Data-Driven, Cooperative Approach for Wind Farm Control: A Wind Tunnel Experimentation

This paper discusses a data-driven, cooperative control strategy to maximize wind farm power production. Conventionally, every wind turbine in a wind farm is operated to maximize its own power production without taking into account the interactions between the wind turbines in a wind farm. Because of wake interference, such greedy control strategy can significantly lower the power production of...

Performance of Disturbance Augmented Control Design in Turbulent Wind Conditions

This paper investigates the use of disturbance models in the design of wind turbine individual pitch controllers. Previous work has used individual pitch control and disturbance models with the Multiblade Coordinate Transformation to design controllers that reduce the blade loads at the frequencies associated with the rotor speed. This paper takes a similar approach of using a disturbance model...

A Shock Tube Driven Transonic Wind Tunnel

A small transonic wind tunnel was designed, constructed and calibrated in order to provide a tool for the study and demonstration of transonic flow phenomena. The wind tunnel makes use of flow properties following the propagation of a shock wave along a tube in order to create the transonic flow. This is in contrast to conventional transonic facilities which are supplied from a reservoir or com...
