Abstract

ABSTRACT: This paper proposes an adaptive fault-tolerant boundary vibration control method designed to resolve unknown failure and stuck actuator problems in the wind turbine blade control process. The blade is modelled as a distributed parameter system described by two coupled partial differential equations. The proposed boundary control achieved the fact that the vibration of the blade can still be suppressed even when the actuator fails, and the bending and torsional deformation is eventually reduced to zero. Based on the Lyapunov direct method, a fact has been confirmed that the stability of the system is guaranteed under the boundary controller. The effectiveness of the controllers is demonstrated by numerical simulations.
