Aiming at solving the problems of low wind energy conversion efficiency and poor robustness when the wind generating set is operating in low wind speed area
a maximum power tracking control strategy based on selfadaptive nonsingular fast terminal sliding mode is proposed. By designing the non-singular fast terminal sliding mode algorithm
the response speed of the wind wheel rotating speed with the wind speed change is improved. To solve the unmodeled dynamic and external noise interference problems occur in the actual wind power generation system
the self-adaptive algorithm is adopted to estimate the uncertainty of the system
thus to strengthen the robustness of the system. Taking a 5 MW wind turbine unit as the research object
the control scheme is simulated on MATLAB/Simulink platform. The simulation results show that
the proposed control strategy has high accuracy and strong robustness
which can make the wind turbine have faster speed response speed and higher wind energy conversion efficiency.
