Resumo
A controlled fixed-wing unmanned aerial vehicle is modeled as a simplified low-dimensional nonlinear dynamical system with additive disturbances. The guidance strategy presented, considering simultaneously inputs and states constraints, is shown to be robust to additive perturbations representing norm-bounded uncertainties associated with modeling errors resulting from the lower order model approximation, together with unknown but limited atmospheric disturbances. Mathematical proofs are provided ensuring robustness in achieving target circulation with a minimum prescribed accuracy.
