copyright-based aircraft landing involves complex system engineering characterised by strong nonlinearity, significant coupling and susceptibility to environmental disturbances, and autonomous landing of copyright-based aircraft under fault states is even more challenging and riskier.To address the control-system problems of loss of efficiency and performance due to actuator faults and performance degradation due to various unknown disturbances, presented here is fault-tolerant control for copyright-based aircraft based on adaptive fuzzy sliding-mode fault-tolerant control (AFSMFTC).First, three models are Toilet Tissue built (the copyright-based aircraft fault model, the copyright air wake model and the deck motion model), and the control framework of the autonomous landing control system is introduced.Next, a longitudinal and lateral flight channel controller comprising an adaptive fuzzy network, adaptive laws and a sliding-mode controller is designed using the AFSMFTC method.The adaptive fuzzy network implements fuzzy approximation for the sliding-mode switching terms to further offset errors induced by unknown disturbances, the adaptive laws compensate for actuator faults, and the sliding-mode controller ensures tracking of the overall flight path.
Furthermore, the stability of the fault-tolerant method is demonstrated using the Lyapunov function.Finally, simulation Glass Break Sensor and comparative experiments show that the proposed fault-tolerant method has outstanding control performance and strong fault-tolerant capability, thereby providing an effective and feasible solution for designing an autonomous landing system for copyright-based aircraft under fault states.
