Phase synchronization of two coupled chaotic systems with internal resonance
内共振系统的混沌同步现象

Phase synchronization of two coupled chaotic systems with 2:1 internal resonance is studied.It demonstrats that,with the increase of coupling strength,the system leads to phase synchronization.However,when further increasing the coupling strength to a threthold,the phenomenon of phase synchronization disappears.By calculating the Lyapunov exponents,it is found that phase synchronization is related to the change of the values of the Lyapunov exponents.
