Wind Turbine Power Capture Control With Robust Estimation Available to Purchase

A robust control scheme to optimize the power capture of a wind turbine is proposed. A novel identification technique is used both to estimate the unknown aerodynamic properties and to regulate the turbine speed. A Lyapunov-based approach is adopted to choose the set point change direction so that power capture can be maximized for the given wind speed and environmental parameters. The set point consists of the turbine tip speed ratio and the turbine blade pitch. The efficacy of the controller is demonstrated through simulation.
