| 英文摘要 |
| In this paper, the fixed-time consensus problem of nonlinear stochastic multi-agent systems is investigated
under fixed and switched topologies. Firstly, a novel protocol for fixed topology is proposed. The sufficient condition is
provided for solving the fixed-time consensus. By using the stability theory of stochastic differential equation and algebraic
graph theory, the validity of the protocol is proved. Meanwhile, the minimum upper bound of convergence time is given as
well. Then, it is extended to the case of switching topology. The union of designed switching topology subgraphs merely
demand to satisfy the connectivity condition, so that fixed-time consensus is achieved with more general model. Finally,
two simulation examples further verify the effectiveness of the theoretical results. |
