Memristor-based oscillators are of recent interest, and hence, in this paper, we introduce a new Wien bridge oscillator with a fractional-order memristor. The novelty of the proposed oscillator is the multistability feature and the wide range of fractional orders for which the system shows chaos. We have investigated the various dynamical properties of the proposed oscillator and have presented them in detail. The oscillator is then realized using off-the-shelf components, and the results are compared with that of the numerical results. A combination synchronization scheme is proposed which uses more than one driver systems to synchronize with one response system. Indeed, we use two different techniques where the first one consists of splitting the transmitted signals into two parts where each part is loaded in different drive systems, while the second one consists of dividing time into different intervals and loading the signals in different drive systems. Such techniques improve the antiattack capability of the systems when used for secure communication.

具有分数阶忆阻器的简单混沌维恩桥振荡器及其组合同步，可实现高效的抗攻击能力

基于忆阻器的振荡器最近受到关注，因此，在本文中，我们介绍了一种带有分数阶忆阻器的新型Wien桥振荡器。所提出的振荡器的新颖之处在于系统表现出混乱的多重稳定性特征和小数阶范围。我们已经研究了所提出的振荡器的各种动力学特性，并对其进行了详细介绍。然后使用现成的组件实现振荡器，并将结果与​​数值结果进行比较。提出了一种组合同步方案，该方案使用多个驱动程序系统与一个响应系统进行同步。实际上，我们使用了两种不同的技术，其中第一种技术是将传输的信号分为两部分，每个部分都加载到不同的驱动系统中，第二个是将时间划分为不同的时间间隔，然后将信号加载到不同的驱动系统中。当用于安全通信时，此类技术可提高系统的抗攻击能力。
