Self Adaptive Integral-Type Sliding Mode Control for Supporting Structure of a Magnetic Vertical Axis Wind Turbine

Abstract:

Vertical axis wind turbine (VAWT) plays one of the important roles in wind power equipments. When joining the magnetic levitation technology, the VAWTs can effectively reduce the friction torque to improve startup performance and increase the power coefficient. At the same time, the mechanical vibration can be reduced, and its actual functioning time can be extended. In this paper, the structure, working principle and mathematical model were introduced respectively with an intention to present the magnetic supporting structure of a VAWT. Then the self adaptive integral-type sliding mode control (AISMC) was offered and designed. Compared with convention-al PID control, the simulations show that the system under the AISMC control has a better dynamic response and robust characteristic.
