Abstract:

The modeling and control of the telescopic morphing aircraft for morphing-aided maneuver are studied in this paper. The relationships between the aircraft wingspan-varying and the aerodynamic parameters are analyzed. Taking the wingspan-varying as an extra operation, the dynamic model of the morphing-aided maneuver is constructed. To deal with the high nonlinearity and the hybrid disturbances, a novel feedback linearization based non-singular dynamic terminal sliding mode control (NDTSMC) approach is proposed. The convergence of the aircraft states within a finite time is guaranteed by the NDTSMC, and the chattering is eliminated by integration of the switch control signals. The simulation results show that the control precision and the robustness of the morphing aircraft are improved by the NDTSMC with a better chattering elimination. The maneuverability and the disturbance rejection capacity of the morphing aircraft with morphing-aided maneuver are demonstrated stronger than the conventional ones.
