Fault-Tolerant Directional Control of Unmanned Airship with Actuator Failure and External Disturbance
This paper investigates the problem of fault-tolerant directional attitude control for unmanned airship with actuator failure and external disturbance.On the basis of Lyapunov stability theory,an adaptive robust fault-tolerant controller is proposed,which can guarantee that the closed-loop system is asymptotically stable in the presence of rudder failure and external disturbance.Compared with the existing work of fault-tolerant control (FTC) for airship,the fault-tolerant control algorithm proposed in this paper is not dependent on fault detection and isolation (FDI) mechanism.An example is provided to illustrate the effectiveness of proposed method.
