A Fixed-Time ESO Based Self-Healing Attitude Control

This paper investigates a novel Fixed-time ESO based self-healing attitude control method for trans-medium aircraft with damaged actuators to achieve the proper contact between the fuselage and the new medium. How to reconstruct the fault information has become a great challenge. To solve this problem, a novel self-healing attitude controller is proposed. Firstly, a Fixed-time ESO is constructed to achieve fault diagnosis. Subsequently, a self-healing controller is designed to cope with the actuator fault. Furthermore, the stability analysis indicates the convergence stability of the closed-loop system. Finally, numerical comparison results verify that the attitude can converge in the finite time.
