Flying -Wing Aircraft Control Allocation

TLDR: In this article, a nonlinear dynamic inverse theory based control allocation for flying-wing configuration aircraft is proposed, and the attitude-training flight control system based on nonlinear Dynamic Inverse Theory (DIT) is designed.

Abstract: Flying -wing configuration aircraft has multi -control -effector s redundant ly . Especially the innovative drag rudder s a re implemented on it . So the control allocation is s trongly nonlinear and multi -ax es coupl ing . The features and applicabilit y in different flight tasks of several typical control allocation methods were summarized . The multi -objective s optimiz ation method based on nonlinear programming was u tilized because of the new characteristic s of the control allocation for the flying wing configuration aircraft. The differences of control allocation results under different objectives were analyzed. And the attitude -tr acking flight control system based on nonlinear dynamic inverse theory was designed, and the d igital simulation using a six degree -of -freedom nonlinear model of certain flying -wing configuration aircraft was conducted, which demonstrate the applicability f or flying -wing configuration aircraft. The results also indicated that the impacts of different optimizing object ives on flight states were remarkable and different.
