动力系统的高维极限环与耦合诱导同步

Higher Dimensional Limit Cycles and Coupling Induced Synchronization in Dynamical Systems

Satadal Datta, Jayanta Kumar Bhattacharjee, Dibya Kanti Mukherjee

摘要:

极限环(耗散动力系统中相邻周期轨道的吸引子)已被广泛研究,但相应的拟周期轨道的推广很少讨论。本文通过分析一对耦合的非全同Van der Pol振子和Kuznetsov振子来研究“高维极限环”。我们发现,重整化群为基础的方法介绍了陈,Goldenfeld和Oono是理想的适合于分析拟周期类似的极限环。我们还解决夹带问题,在一对强迫和耦合范德波尔振荡器。我们的原则发现,如果两个这样的独立振荡器一个频率夹带和其他没有线性耦合,那么它是可能的,通过耦合产生一个夹带状态。

英文摘要:

Limit cycles (attractors for neighbouring periodic orbits in a dissipative dynamical system) have been widely studied but the corresponding generalization for quasi periodic orbits have rarely been discussed. Here we investigate "higher dimensional limit cycles" by analysing a pair of coupled non identical Van der Pol oscillators and also the Kuznetsov oscillator. We find that the renormalization group based approach introduced by Chen, Goldenfeld and Oono is ideally suited for analysing the quasi periodic analogues of limit cycles. We also address entrainment issues in a pair of forced and coupled Van der Pol oscillators. Our principle finding there is that if two such independent oscillators one with frequency entrainment and the other without are coupled linearly, then it is possible to produce an entrained state via the coupling.
