Study On Synchronization In Multi-scroll Chaotic Attractors

Multi-scroll chaotic attractors of recent research is one of important achievements. The main feature of multi-scroll chaotic attractors is that they exhibit a rich variety of complicated chaotic dynamic phenomena and have many scroll encryption parameters that can be applied to secure communications.The chaotic synchronization of chaotic secure communication is an important condition. Research the multi-scroll chaotic synchronization technique anddesign more multi-scroll chaotic secure communication systems can further improve the performance of chaotic systems and increase confidentiality decode.The multi-scroll chaotic attractors and the synchronization in this paper are mainly talked about.By means of circuits simulation, oretical analysis and numerical calculation the sufficient and correct results of the problems discussed are obtained.This article first to produce several methods of multi-scroll chaotic attractors which are summarized in the paper.By means of numerical simulation and circuit simulation to the multi-scroll chaotic attractors in four-dimensional system.This method is a new nonlinear function through constructing.It don't need carry out complex mathematical derivation in four-dimensional chaotic systems.It can produce a size uniformity of scroll chaotic attractors and overcome the piece wise linear odd function point voltage calculation error-prone faults.Secondly, the synchronization of the two, four and six chaotic attractors in four-dimensiol systems are realized by means of driving-response synchronization method,active-passive syn -chronization method and variable feedback synchronization method.Through theoretical anal -ysis.It is proved that the synchronization can be realized with the three synchronization meth -ods applied in four-dimensional systems of the multi-scroll chaotic attractors.The conclusion is identical by the computer simulation.In addition, it can get good synchronization results th -rough designing the circuit and using Pspice simulation circuit.Based on circuit simulation experimental research. The result of the multi-scroll chaotic attractors in four-dimensional chaotic system of the circuit and their synchronization which will undoubtedly provide important basis for further research.
