摘要

Air cushion landing system (ACLS) can help airplane realize amphibious take-off and landing. Even so, vehicle with the ACLS is more susceptible to uncertainties such as crosswind, unmolded dynamics and high nonlinearities than other take-off/landing methods, resulting in difficulty escalation for the tracking deviation correction (TDC) control. In this paper, to deal with the TDC problem for the airplane, a disturbance attenuation predictive control scheme is proposed. To enhance system robustness, a disturbance observer (DO) is designed to attenuate uncertainties through an online feedback compensation way. To degrade the influences such as input surging/saturation and large overshoot induced by sudden occurrence of uncertainties, a type of predictive controller considering tracking error and input power is developed. Contrast simulations are conducted to show the superiorities of the proposed control scheme. (C) 2021 Elsevier Masson SAS. All rights reserved.
