Abstract
Abstract. The paper considers the analysis and synthesis of an autoland flight control system of a tailless UAV in lateral motion stabilization mode during runway roll-out. The UAV lateral motion is unstable and, consequently, stability region of the closed loop is bounded due to control constraints. The maximum stability region is computed. The scheduled-gain static controller, obtained using LMI, is used for lateral motion stabilization during runway roll-out. The simulation results are presented using high-fidelity nonlinear aircraft model.Keywords:
