Dynamic Inversion-Based Adaptive Fault Tolerant Control for Heavy Launch Vehicles with Non-lethal Actuator Faults

This paper proposes the dynamic inversion-based adaptive fault tolerant control for heavy launch vehicles with non-lethal actuator faults. Firstly, the attitude dynamics model and fault model of heavy launch vehicles are formulated. Secondly, based on the dynamic inversion theory, the ideal controller is designed. Then, the controller and adaptive law are designed for actuator gain faults and bias faults. Meanwhile, the Lyapunov function is constructed to prove that all signals in the closed-loop system are uniformly convergent. Finally, numerical simulation results show the effectiveness and the satisfactory performance of the proposed control algorithm.
