Terminal Sliding Mode Control for Wind Energy Conversion System Based on Constant Tip Speed Ratio

Abstract:

In this paper, the terminal sliding mode (TSM) control technique is used to solve the solution sought for the maximum power point tracking (MPPT) of wind energy conversion system. In order to realize the control strategy, the wind energy conversion system (WECS) is regarded as a part of the constructed high order system. Based on the constant tip-speed ratio (TSR), selecting the appropriate state variables and treating rotational speed as the object researched, the control scheme for the MPPT of wind turbine can be achieved by using the terminal sliding mode control technique. The simulation carried out shows that the system tracking efficiency can be greatly improved and the power factor and tip speed ratio are very close to the optimal value in this solution.
