Abstract :
Morphing wing has a significant impact on dynamic characteristics of very flexible aircraft (VFA), effective control of VFA is premised on accurate control of wing shape. A simplified control model for the morphing wing dynamics of VFA was established. A new controller architecture used for wing shape control was proposed based on NDI and NESO method. Lyapunov function was introduced to discuss the controller parameter tuning principle. The simulation results show that the robust controller has high performance for tracking the wing dihedral command, and improve the robustness to disturbing effect.
