Fault Tolerant Control for UAV with Finite-Time Convergence
In this paper,the finite-time fault tolerant control(FTC)of attitude stabilization is developed for attitude dynamical system of a hypersonic unmanned aerial vehicle(UAV)with actuator loss-of-effectiveness(LOE)fault.First,the hypersonic UAV non-linear attitude dynamics are described.A finite-time controller is designed on the basis of nonsingular terminal sliding mode(NTSM)control technique for the UAV attitude dynamical system.Then based on the technique of dynamic surface control,the fault tolerant control plan is proposed,which ensure the closed-loop dynamical systems of UAV converge to a stable state in a finite-time in the case of the actuator LOE faulty.Finally,some simulation results are presented to demonstrate the efficiency of the proposed method.
