This paper deals with the design of LQG controllers for pitch regulated, variable speed wind turbines where the controller is used primarily for controlling the pitch angle through a collective pitch angle in the high wind speed in order to guarantee the power regulation. A control structure based on a linear model approach is presented to take into account system non linearities and evolutions of...
This paper presents a control scheme based on fuzzy logic for adjusting the turbine speed so as to track the maximum power point. The power output from wind turbines varies nonlinearly with the wind speed, the speed of the turbine blade tips and the blade pitch angle. At a given pitch angle and wind velocity, maximum power is obtained at a specific turbine angular speed. Since wind speeds typically...
This paper deals with the design of LQG controllers for pitch regulated, variable speed wind turbines where the controller is used primarily for controlling the pitch angle through a collective pitch angle in the high wind speed in order to guarantee the power regulation. The performance of the control is compared to that of a PID controller using the SUT-1MW wind turbine and wind model. The results...
