This document derives stable on-line approximation based control algorithms for application to the longitudinal control (7, LY, Q, V) for an uninhabited combat air vehicle (UCAV) to achieve accurate command tracking in the presence of significant nonlinear model error.Abstract:
This document derives stable on-line approximation based control algorithms for application to the longitudinal control (7, LY, Q, V) for an uninhabited combat air vehicle (UCAV). The objectives of the control approach are to stabilize the aircraft dynamics and achieve accurate command tracking in the presence of significant nonlinear model error. This error could be due to decreased modeling effort during the design process or the result of events that occur during the vehicle flight (i.e., battle damage). Lyapunov stability analysis and simulation demonstrations of the achieved performance are included.read more

Nonlinear Flight Control Design Using Constrained Adaptive Backstepping
TL;DR: In this article, an adaptive backstepping flight control law for the F-16/MATV (multi-axis thrust vectoring) aircraft is discussed, which tracks reference trajectories with the angle of attack a, the stability-axes roll rate p s, and the total velocity V T. Furthermore, the sideslip angle β has to be kept at zero.
