Abstract: Research under the respective circumstances of fixed coupling coefficient and the dynamic coupling coefficient, the range of the coupling coefficient that makes the synchronization of chaotic systems. Depending on differences of the dynamic coupling signals and by selecting appropriate coupling parameters, dynamic synchronous coupling of chaotic systems can be achieved. With the aid of ODE45 function in the matlab software to solve the lorenz system chaotic equation and draw the image to observe the phenomenon of synchronous coupling, the range of the coupling coefficient in the dynamic synchronization is debugged.
