Abstract

The invention belongs to the field of nonlinear power system, and in particular relates to a synchronous control method of complex network and its application in image encryption. The synchronization method includes the following steps: Step S1: According to the target synchronization state that the n-dimensional fractional time-varying coupling complex network needs to achieve, establish an equation that characterizes the target synchronization state; Step S2: Design a synchronization controller, and the method is subdivided into: Step S21: Define the error of projection synchronization; step S22: design an adaptive controller according to the error equation of projection synchronization; step S23: design the adaptive coupling strength; step S3: use the designed adaptive coupling strength to compare the coupling strength in the complex network model Make adjustments and introduce synchronous controllers into each node of the complex network. The invention can realize the synchronization between each node and the synchronization target in the complex network, solve the problem that the synchronization cannot be performed or the synchronization is easily interrupted due to the coupling effect between the nodes, and based on this, the encryption and decryption processing of the image can be realized.

Background technique

[0002] Complex network is a modeling tool that can effectively describe the World Wide Web, epidemic transmission network, genetic network, communication network, neural network, biological network, etc. Complex networks usually consist of many interconnected nodes, each with complex dynamic behavior. At the same time, the dynamic characteristics of complex networks are more complex due to the interactions between nodes. Since complex networks are widely used in practical scenarios, their dynamic behavior has attracted the attention of researchers. At present, there are many s...
