| 英文摘要 |
| In this paper, the secure adaptive consensus control problem is considered for a class of uncertain nonlinear
multi-agent systems under unknown control direction against uncertain cyber attacks. Cyber attacks destroy the real data of
sensors, so that the real information of the system cannot be obtained and cannot be directly used for control design. In this
paper, a new set of auxiliary variables is constructed to eliminate the impact of cyber attacks. Furthermore, the considered
systems include more general uncertainties, namely, the unknown control direction, the uncertain constant parameters
and the uncertain cyber attacks. These uncertainties are coupled together during the control design process. To tackle the
coupled uncertainties, Nussbaum-type functions are used and an adaptive law is designed, which immensely reduces the
system complexity. By constructing a common Lyapunov function for all subsystems, a secure protocol is developed to
guarantee that all the outputs of the multi-agent systems achieve the asymptotical consensus against cyber attacks under
arbitrary switching. Finally, an example is presented to verify the effectiveness of the proposed method. |
