Robust Nonlinear Control of Piloted Tailless Fighters

Abstract

The theme of this research has been to develop effective strategies for the design and analysis of flight control systems for tailless fighter aircraft. In our quest to understand the fundamental issues in the aggressive maneuvering of high performance fighter aircraft, we have developed tools and techniques, and the appropriate supporting theoretical results, for the study and analysis of high performance maneuvering systems. We have developed a simplified flight dynamics model, the coordinated flight vehicle (CFV). Exploiting the geometric structure of the CFV, one may easily explore the space of aggressive flight maneuvers. We have developed an optimization based, trajectory morphing technique by which CFV maneuvers may be used to parametrize the achievable flight maneuvers (i.e., maneuvers that satisfy given high fidelity aircraft model dynamics). We have also developed theory and algorithms to allow these model based optimization techniques to used online, in a receding horizon fashion. As a theoretical bonus, we have obtained new results on the structure of the trajectory manifold of a nonlinear system.
