ScholarBank@NUS Repository.||Abstract:||Design of kernel control laws is an important step in autonomous flight control design for UAVs, because the function of kernel control laws is to guarantee asymptotical inner-loop stability of aircraft motion relative to the surrounding air. The design can be further complicated by nonlinear flight dynamics. In this paper, we propose a hierarchical dynamic inversion (HDI) method for design of the kernel control law for a fixed-wing UAV based on quasi-steady states. HDI is more generally applicable to some non-affine nonlinear systems. The designed kernel control law is incorporated into an autonomous flight controller and verified in simulation based on the high-fidelity 6-DOF nonlinear model of a UAV. The simulation results demonstrate that the UAV with the designed kernel control law successfully execute super maneuver and is robust against actuator gain variation. © 2008 by the American Institute of Aeronautics and Astronautics, Inc.||Source Title:||AIAA Guidance, Navigation and Control Conference and Exhibit||URI:||http://scholarbank.nus.edu.sg/handle/10635/111577||ISBN:||9781563479458|
