【Abstract】 Based on the analysis of the feature of synchronized system,a combination of subsection control and non-linear feedback control to realize the synchronization of chaos system is introduced.Synchronization is realized by choosing the appropriate controlling law and coefficient.The outcome is that synchronization is much quicker and the synchronized error is much smaller than before.Furthermore,the validity of the approach is proved through the numerical simulations.更多还原
