Design of Robust Adaptive Flight Controller Based on Nonlinear Dynamics

A synthesized nonlinear robust flight control scheme is proposed for modern complex warfare environment. For overcoming the unfavorable influence which caused by the uncertainty of system, time delays and unmodelled dynamics, based on the basic dynamic inversion flight controller, the synthesized nonlinear robust flight controller is designed by using multi-layer perception neural network and dynamic nonlinear damping control. The online adjusted parameters of neural network and the inhibition of dynamic nonlinear damping control are introduced to make the flight system to track the desired command signal and satisfy the given performance index. Finally, the compensation ability of the designed robust flight control system is demonstrated by flight simulation in the condition of time delays and the failure of horizontal tail.
