| Abstract: | The synchronization problem of the three species food chain in biology was studied in the paper.The global asymptotic synchronization was attained based on the theory of time-varying systems and bi-directionally linear coupled between two food chain systems.The boundedness of the three species food chain and its coupler system were proved based on the comparison theorem.Two different numerical algorithms were adopted to verify the results of theoretical calculation and explain the biological significance. |
