Ph.D. project. Ma Xin. The main idea in this project is to maximize some performance criteria by using adaptive control methods. The purpose of the controller design is to increase the efficiency of some processes. The extremum control is related to optimization techniques. A wind turbine is taken as an example for applying adaptive extremum control. In order to design a high performance control system, a detailed model of dynamic behaviour of the wind turbine is needed. Such a model can be achieved from two approaches: theoretical method and identification techniques. In this yaer the nonlinear theoretical model is established by using simulink, the system is modelled from known physycal interpretations. Some control methods require the knowledge of wind speed, but it is impossible to measure the effective wind speed on the rotor plane. Therefore estimation of wind speed on the rotor plane is considered by using the wind turbine as wind measuring device. Several estimation methods are investigated.
