Reliability analysis of an automatic carrier landing system based on predefined-time fault-tolerant control under air-wake disturbances and actuator faults

Purpose This study aims to evaluate the reliability of an automatic carrier landing system using predefined-time fault-tolerant control, focusing on its performance under air-wake disturbances and actuator faults. Design/methodology/approach The research utilizes a predefined-time fault-tolerant control framework with a prescribed-time extended state observer. Simulations are conducted to assess the system’s response to disturbances and faults, comparing reliability metrics like fault tolerance and convergence speed. Findings The results show that the predefined-time fault-tolerant control improves system reliability, offering faster state estimation and better fault-handling capabilities compared to other control methods. The system maintains stable performance under severe disturbances. Originality/value Different from other control methods, this study provides a robust control solution for enhancing the safety and reliability of carrier landings, offering valuable insights for future naval aviation and aerospace control systems.
