Vector Backstepping Design for Flight Control
2007 (English)In: Proceedings of the 2007 AIAA Guidance, Navigation, and Control Conference and Exhibit, 2007Conference paper (Other academic)
A backstepping design for an aircraft described by rigid body dynamics is proposed. The system states are the unit velocity vector and the angular velocity in a body-ﬁxed coordinate system. The result can be viewed as a multi-variable controller for angle of attack, sideslip angle, and velocity vector roll rate. The backstepping design is performed on the rigid body dynamics described on vector form. The resulting controller achieves convergence to a desired state from almost all starting points. Guidelines are given for tuning the controller to aﬀect the characteristics of the short period mode, the roll mode and the dutch roll mode. A coupled high angle of attack, high roll rate maneuver is simulated using a simpliﬁed aircraft model to illustrate the design.
