The present invention discloses an annular coupling oscillator system for realizing explosive synchronization and a method for realizing explosive synchronization in an annular coupling oscillator system. Special frequency spatial distribution is introduced into an annular coupling oscillator system to control parameters such as a frequency difference weight coefficient, coupling intensity and the like to allow the coupling oscillator system to transit to an explosive synchronization state from an uncorrelated state. Coupling effect intensity parameter intervals required for realizing explosive synchronization are determined through theoretical analysis, a condition with frequency difference weight coupling is further developed, and the annular coupling oscillator system realized the prediction and realization of the parameter intervals with explosive synchronization. The theory analysis method employed by the invention can determine the influence factors and the parameter intervals from mixed explosive synchronization to classic explosive synchronization in the annular coupling oscillator system so as to have guidance meanings for better understanding and realization of the self-organizing dynamics behavior of the annular coupling oscillator system in a regular network structure.
