The traditional method of chaotic phase synchronization is usually high of complexity, low accuracy of warning. According to these problems, this paper proposes one chaotic synchronization algorithm based on two coupled oscillators. Firstly, the model of chaotic synchronization and detection of two coupled oscillators equation are given. And then, the nonlinear dynamics of coupled chaotic oscillators model are in-depth analysis, and the noise immunity and stability analyzes of the algorithm are proved in paper. Finally, the power carrier signal simulation results are demonstrated for the effectiveness of the algorithm.
