Fault-Tolerant Attitude Control Incorporating Reconfiguration Control Allocation for Supersonic Tailless Aircraft

This paper presents a fault-tolerant attitude control scheme, incorporating reconfiguration allocation for supersonic tailless aircraft subject to nonlinear characteristics, actuator constraint, uncertainty, and faults. The main idea is propose an incremental closed-loop coupled with basic backstepping controller, achieve control. Based on the virtual input generated by firstly, method adopted deal characteristics constraint. Secondly, distribution error feedback loop constructed in enhance robustness against uncertainty of effectiveness matrix. Thirdly, matrix reconstructed different kinds fault information faults, proper combination deflections accurate command tracking. stability proposed scheme guaranteed Jury criterion Lyapunov analysis. Finally, comparison three existing approaches, simulation results two cases are provided show scheme.
