通过在非线性极限环振子中加入相同的噪声序列，可以实现非线性极限环振子的相位同步，这种同步称为噪声诱导同步。在我们以前的研究中，我们已经证明，即使加入自然的环境噪声或波动，非线性振荡器的同步。由于位于附近的传感器测量的自然波动，如温度，湿度和声音具有高度的互相关，安装在独立设备中的振荡器可以通过这些自然信号同步。在本文中，我们研究的同步性能与我们提出的方法的参数，如噪声输入幅度和输入间隔的变化。实验结果表明，强噪声对快速同步有效，弱噪声对维持同步有效，通过调整参数可以提高自然同步的性能。
The phases of nonlinear limit-cycle oscillators can be synchronized by adding identical noise sequence to each of them, which is called noise-induced synchronization. In our previous researches, we have shown that the nonlinear oscillators synchronize even by adding natural environmental noise or fluctuations. Because the natural fluctuations, such as temperature, humidity and sounds, measured by the sensors located in nearby have high cross-correlation, the oscillators installed in independent devices can be synchronized by those natural signals. In this paper, we investigate the synchronization performance with changing the parameters of our proposed method, such as the noise input amplitude and the input interval. Our experimental results show that strong noise is effective for quick synchronization and weak noise is effective for sustention of the synchronization, and the performance of the natural synchronization can be improved by tuning the parameters.
