Abstract: This paper deals with the development of a non-singular fast terminal sliding mode controller for maximum power point tracking of wind energy conversion system. The studied system is made up of a wind turbine coupled to a permanent magnet synchronous generator, a three-phase diode rectifier and supplying through a boost converter, a resistive load. The principle of the control scheme is based on electrical measurements and the choice of a suitable sliding surface. This approach presents a good transition response, a low tracking error and a very fast reaction against wind speed variations compared to the traditional sliding mode controller. The effectiveness of the proposed control scheme is demonstrated by numerical simulations under different climatic conditions.

Keywords: wind energy process; maximum power point tracking; robust control; non-singular fast terminal sliding mode controller; Lyapunov function.
