摘要：AbstractThis paper proposes a fractional-order sliding-mode fault-tolerant control scheme for unmanned airship in the presence of actuator faults. In the control scheme, a control-oriented unmanned airship model is first developed by considering the unexpected actuator faults. Then, fractional-order calculus and sliding-mode control strategies are integrated to achieve refined fault-tolerant performance. Fixed-time sliding-mode disturbance observer is employed to estimate the fault-induced uncertainty. Moreover, Lyapunov stability analysis is conducted to show that the faulty unmanned airship can track the desired reference even in the presence of actuator faults. Simulation results are presented to show the effectiveness of the proposed control scheme.
