Abstract:
The large-scale morphing aircraft can change its shape dramatically to perform high flight performance. To ensure the transient stability of aircraft in the morphing process, a novel gain-scheduled control method is investigated numerically in this paper. Based on quasi-steady assumption, the linear parameter varying (LPV) model of the morphing vehicle is derived from its nonlinear equation. Afterwards, by solving a set of linear matrix inequalities along with the bound of the morphing rate via slowly varying system theory, the designed controller which considers the transition stability during the morphing process is obtained. Finally, the transition process simulations of the morphing aircraft are performed via the changes simultaneously in both span and sweep, and the results demonstrate the effectiveness of the proposed controller.
