本文研究了三个不同混沌系统的有限时间随机组合同步。基于自适应技术和维纳过程的性质，得到了一个新的充分条件，以确保在随机扰动下的组合同步。此外，提出了一种基于三个不同系统（即洛伦兹系统、陈系统和吕系统）在具有不确定性、未知参数和随机扰动情况下的自适应组合同步的保密通信方案。仿真结果表明了所提方法的可行性。
In this paper, the finite-time stochastic combination synchronization of three different chaotic systems is investigated. Based on the adaptive technique and the properties of Weiner process, a novel sufficient condition is obtained to ensure combination synchronization under stochastic perturbations. Moreover, a secure communication scheme based on the adaptive combination synchronization of three different systems, i.e., the Lorenz system, Chen system, and Lü system, with uncertainties, unknown parameters, and stochastic perturbation is presented. The simulation results show the feasibility of the proposed method.
