In this paper, a novel kind of compound synchronization among four chaotic systems is investigated, where the drive systems have been conceptually divided into two categories: scaling drive systems and base drive systems. Firstly, a sufficient condition is obtained to ensure compound synchronization among four memristor chaotic oscillator systems based on the adaptive technique. Secondly, a secure communication scheme via adaptive compound synchronization of four memristor chaotic oscillator systems is presented. The corresponding theoretical proofs and numerical simulations are given to demonstrate the validity and feasibility of the proposed control technique. The unpredictability of scaling drive systems can additionally enhance the security of communication. The transmitted signals can be split into several parts loaded in the drive systems to improve the reliability of communication.
本文研究了四类混沌系统的一种新的复合同步，其中驱动系统被分为两类：比例驱动系统和基础驱动系统。首先，基于自适应技术，得到了四个忆阻器混沌振荡器系统实现复合同步的充分条件。其次，提出了一种通过自适应复合同步实现的四个忆阻器混沌振荡器系统的安全通信方案。给出了相应的理论证明和数值模拟，以验证所提出的控制技术的有效性和可行性。比例驱动系统的不可预测性可以进一步提高通信的安全性。传输信号可以分成几部分加载到驱动系统中，以提高通信的可靠性。
