Robust adaptive variable speed control of wind power systems without wind speed measurement
The stochastic and immeasurable nature of wind imposes significant challenge to control design for wind turbine (WT) systems. This work presents a robust adaptive approach to achieve variable speed tracking control of WT wind turbine without the need for wind speed measurement. The adverse effect arisen from wind is accommodated by the robust and adaptive control algorithms based on virtual parameter concept. A hill-climb searching algorithm is exploited to provide desired rotor speed signal, avoiding wind speed measurement. The stability of the proposed control scheme is authenticated by Lyapunov stability theory. The effectiveness and the benefits of the proposed approach are validated and demonstrated by numerical simulation.
