14 Dec 2004 | Journal: | Physical Review E 67, 056205/1-8 (2003) | Subject: | Chaotic Dynamics | nlin.CD | Abstract: | We derive the normal form for the delay-induced Hopf bifurcation in the first-order phase-locked loop with time delay by the multiple scaling method. The resulting periodic orbit is confirmed by numerical simulations. Further detailed numerical investigations demonstrate exemplarily that this system reveals a rich dynamical behavior. With phase portraits, Fourier analysis and Lyapunov spectra it is possible to analyze the scaling properties of the control parameter in the period-doubling scenario, both qualitatively and quantitatively. Within the numerical accuracy there is evidence that the scaling constant of the time-delayed phase-locked loop coincides with the Feigenbaum constant $delta approx 4.669$ in one-dimensional discrete systems. | Source: | arXiv, nlin.CD/0501031 | Services: | Forum | Review | PDF | Favorites |
