Optimal Guaranteed Cost Control Design for Lateral Aircraft Dynamics with Uncertainties and Time Delay

Abstract

This paper presents an optimal guaranteed cost controller for aircraft lateral dynamics. A linear model with parametric uncertainties and time delay is first used to establish the proposed control scheme. The Lyapunov stability theorem and linear matrix inequality are then used to design an optimal state feedback control law for application to the lateral aircraft dynamics which resolves the instability caused by said uncertainties and time delay. The effectiveness and robustness of the model are demonstrated via simulation.
