Event-Triggered Incremental Fault-Tolerant Control: Recovery Performance and Convergence Time Guarantee

To ensure both recovery performance and convergence time, this paper proposes a novel incremental FaultTolerant Control (FTC) integrated with an event-triggered mechanism. A function with prescribed performance is designed to constrain the tracking errors, guaranteeing that they remain within the prescribed safety boundary at all times. By incorporating the prescribed-time control theory into incremental control, the tracking errors recover to a stable state within a user-defined time. To reduce computational burden, an event-triggered mechanism is further integrated to the proposed prescribed-performance and prescribed-time incremental FTC to avoid unnecessary control updates. Finally, based on the proposed incremental FTC, the angular rate controller for fixed-wing aircraft is developed to improve flight safety. Simulation results demonstrate that the developed FTC effectively overcomes the asymmetric wing damage, achieving the desired recovery performance and convergence time while significantly reducing computational cost.
