我们指出,对于受噪声影响的振荡器,即使对于弱噪声,传统的相位方程也不是一个合适的近似。提出了一种适用于弱高斯白噪声振荡器的减相方法。数值证据表明,相方程能很好地逼近原振子的动力学特性。此外,我们表明,在一般情况下,噪声会引起振荡器频率的移位,并讨论其对夹带的影响。
We point out that for an oscillator subjected to noise the conventional phase equation is not a proper approximation even for weak noise. We present a phase reduction method valid for an oscillator subjected to weak white Gaussian noise. Numerical evidence demonstrates that the phase equation properly approximates dynamics of the original oscillator. Moreover, we show that, in general, noise causes a shift of the oscillator frequency and discuss its effects on entrainment.
