Usually, complete synchronization (CS) is regarded as the form of synchronization proper of identical chaotic systems, while generalized synchronization (GS) extends CS in nonidentical systems. However, this generally accepted view ignores the role that the coupling plays in determining the type of synchronization. In this work, we show that by choosing appropriate coupling strategies, CS can be observed in coupled chaotic systems with parameter mismatch, and GS can also be achieved in coupled identical systems. Numerical examples are provided to demonstrate these findings. Moreover, experimental verification based on electronic circuits has been carried out to support the numerical results. Our work provides a method to obtain robust CS in synchronization-based chaos communications.
通常，完全同步（CS）被视为相同混沌系统特有的同步形式，而广义同步（GS）则将CS扩展到非相同系统。然而，这种普遍接受的观点忽略了耦合在确定同步类型中所起的作用。在这项工作中，我们表明，通过选择适当的耦合策略，可以在具有参数失配的耦合混沌系统中观察到CS，并且在耦合相同系统中也可以实现GS。提供了数值示例来证明这些发现。此外，还进行了基于电子电路的实验验证以支持数值结果。我们的工作为在基于同步的混沌通信中获得鲁棒的CS提供了一种方法。
