Abstract

This paper focuses on flight controller design for the morphing aircraft which using the swept-back wing. In this paper, the nonlinear morphing aircraft is modeled and the longitudinal mathematical equations are extracted. And the nonlinear dynamic inversion (NDI) flight controller is designed for the longitudinal mathematical model. For solving the problem of dynamic inverse error caused by modeling error in flight control, the control law is improved by adding an additional feedback in the channel of nonlinear cancellation. And to a certain extent, the influence caused by interference forces and moments and non-linear cancellation errors are eliminated. Two simulation experiments are designed for the fixed and morphing configuration. The results of them show the NDI controller has a good performance of tracing and certain robustness for the morphing aircraft.
