Fuzzy gain scheduled output feedback control for variable-speed variable-pitch wind turbine
نویسندگان
چکیده
This paper proposes a fuzzy gain scheduled output feedback control for variable-speed variable-pitch wind turbine in full load region. The proposed method is based on modeling the nonlinear system as a family of systems linearized around a specific operating point. The goal is to design optimal PI controllers based on linear models and a fuzzy scheduler. The parameters of each PI controller are optimized using PSO algorithm. At each sampling time, the scheduler assigns weights to each local PI controller. The weighted sum of local PI controller outputs is used as an input control for manipulating the pitch angle to maintain the speed generator around its rated value. The effectiveness of the proposed controller has been proven in the Matlab / Simulink environment.

Designing a fuzzy PI^lambda controller to control the pitch angle in wind turbines under variant speed
One of the main tasks of the control systems in the wind turbines is to maintain the power of the wind when its wind speed proceed its nominal value. Because the failure to maintain the power in its nominal value in the region of the turbine curve damages the turbine and increases the mechanical stress. This object is obtained by controlling the pitch angle in the third region of the turbine cu...

The Output power of wind turbine is determined by wind speed. The Output power can be adjusted by controlling the generator speed and pitch angle of wind turbine. When the wind speed below the wind turbine rated, the output power of generator can be maximized by controlling the generator speed at point of maximum power coefficient.
