Title:Design and simulation of the distributed adaptive synchronous control of complex networks
Abstract Complex networks are large scale networks with complex topological structures and dynamical behaviors. Although the theories of complex networks in recent years have been made major developments ,and scientists also have made remarkable achievements. Complex systems research has still been considered to be the forefront of science and technology in the 21st century strategic research topics.Among them, the synchronization of the dynamic behavior of complex systems becomes an important research topic of Control Engineering.
The main study in this thesis is pided into the following sections. Firstly, We describe the structure and dynamics model of complex network,derive and calculate distributed adaptive synchronous control of complex networks.Then,the algorithm is applied to complex networks composed by Chua’s circuit nodes.With the knowledge of MATLAB,we build the model of the Chua’s circuit nodes and the distributed adaptive synchronous algorithm in SIMULINK.Through the debugging and comparison of the simulation platform,We are able to understand the inherent mechanism of complex systems’ adaptive synchronization.After simulation,we can analysis of simulation results by changing to a different value of the parameter or adding the node perturbation.Through this,we can find the affect of interference of the external environment and uncertainty in system parameters.Finally,we can further optimize the synchronization control strategy.
