Abstract:Disturbance rejection algorithm based on model reference adaptive control (MRAC) augmentation is investigated for uncertain turbulence disturbances. A stable adaptive control scheme is developed based on lower diagonal upper (LDU) decomposition of the high frequency gain matrix, which ensures closed-loop stability and asymptotic output tracking. Under the proposed control techniques, the bounded stability is achieved and the controller is able to remain within tight bounds on the matched and unmatched uncertainties. Finally, simulation studies of a linearized lateral-directional dynamics model are conducted to demonstrate the performance of the adaptive scheme. © 2017, Editorial Department of Transactions of NUAA.
