快慢系统多频振荡的动力学分岔
Dynamical bifurcation of multi-frequency oscillations in a fast-slow system
摘要:
本文研究了一个由快相变量和慢变参数组成的系统的不变环面分岔的动力学对应。我们表明,在这样的系统中,由于参数的缓慢演变,出现从阻尼振荡到多频的,渐近接近不变环面上的运动的瞬态过程。
英文摘要:
We study a dynamical counterpart of bifurcation to invariant torus for a system of interconnected fast phase variables and slowly varying parameters. We show that in such a system, due to the slow evolution of parameters, there arise transient processes from damping oscillations to multi-frequency ones, asymptotically close to motions on the invariant torus.
