Output Feedback Synchronization Control Method for Coupling Chaotic System

The synchronization method of two same nonlinear systems is discussed based on the passive theory. It is proved that two chaotic systems can be synchronized with output feedback control law if they are all semi-passive systems. The sufficient condition of the existence of output feedback control law as well as the adaptive adjusting algorithm of synchronization are given.Taking Lorenz system as an example, the feedback control law and adaptive algorithm are validated in the simulation.
