Title:
OSCILLATOR SYSTEM SYNCHRONIZATION DETECTION SYSTEM, SYNCHRONIZATION DETECTION DEVICE, AND SYNCHRONIZATION DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/079895
Kind Code:
A1
Abstract:
A synchronization detection device 20 is constituted by: a pseudo-vorticity matrix calculation unit 21 that receives phase time-evolution information from an oscillator system 10 including a finite number of oscillators and calculates a matrix, the elements of which are numerical values obtained by discretizing a phase difference acquired by time evolution of two oscillators; a synchronization graph generation unit 22 that generates a synchronization graph which visualizes two-point synchronization by graph representation; a partial synchronized set detection unit 23 that detects a plurality of partial sets of oscillators which partially synchronize and have no common parts in the set of the finite number of oscillators in the synchronization graph; and a synchronization index calculation unit 24 that uses a calculation result of the calculation by the pseudo-vorticity matrix calculation unit 21 and the partial synchronized sets detected by the partial synchronized set detection unit 23, so as to generate an index which characterizes the partial synchronization in the oscillator system.
