Synchronization control and its application for the unified chaotic system based on chaos observer
统一混沌系统的混沌观测器同步控制及其应用

According to the principle of phase-space reconstruction of a continuous time chaotic system by a single variable and its derivative,the synchronization of a unified chaotic system is investigated by employing the chaos observer synchronization method.A theorem about chaos observer synchronization of unified chaotic system is put forward based on the stability rule for continuous systems.Applying this synchronization method to security communications,we designed a new scheme of chaotic masking security communications based on the technology of time division multiple,and carried out its performance analysis.Simulation results on Matlab 6.5 confirm that both the synchronization approach and the security communications scheme are effective.
