This article focuses on the control issue of flapping wing micro air vehicles (FWMAVs) with wing damage, model uncertainties, external disturbances, and input saturation. A fault model is first established based on a detailed and systematic analysis of effects on aerodynamic forces and moments of FWMAVs caused by wing loss. Based on the fault model, a fixed-time adaptive fuzzy fault-tolerant control strategy is developed by combining an adaptive scheme, a fixed-time control technique, and a fuzzy logic approximation technique. The present one can effectively accommodate wing damage without requiring any prior information about the damage and can render the tracking error to converge to a small neighborhood of the origin within a fixed time. Several significant lemmas are developed to facilitate stability analysis. The fixed-time stability of the resulting closed-loop systems is rigorously proved through the proposed lemmas and the Lyapunov technique. Numerical simulations of several fault cases validate the effectiveness of the present one.
