摘要：This paper investigates a finite-time backstepping control for robust stabilization of fractional-order hydroturbine governing system. We assume that the controlled system is perturbed by external disturbance, the bound of external disturbance to be unknown in advance. Through designing the virtual controllers step by step, then the appropriate actual controller is obtained. The fractional-order stability theory is used to shown the correctness of the proposed control strategy, and finally numerical simulations have been implemented to confirm the effectiveness and feasibility of the presented finitetime backsteping method.
