Summary:
Noise-induced synchronization is a phenomenon that the nonlinear oscillators synchronize by adding common noise to each of them. In our previous researches, we have already confirmed that synchronization of the oscillators also occurs even by adding natural environmental fluctuations obtained in close, which have high cross-correlation. In this paper, we investigate parametric dependence of noise input method by changing amplitude and interval of noise input. By our numerical experiments using real data and white Gaussian noise, it is confirmed that strong noise is effective for fast success of synchronization and weak noise is effective for long retention of synchronization. Futhermore, our experimental results show that there are optimal parameter settings to improve the performance of synchronization, even when using the natural environmental fluctuation.
