The hopf bifurcation with bounded noise
WebJul 9, 2024 · The effect of noise strength on increasing the peak amplitude of the oscillations is prominent near the Hopf bifurcation (weak values of W E E), but very weak far from it. For strong noise [(e) and (f)], the amplitude peak and variability increase again for all W E E. Other parameters are as in Fig. 1. Reuse & Permissions WebMar 1, 2024 · Random physical intensity can promote the occurrence of Hopf bifurcation, noise intensity can change the magnitude of the limit cycle amplitude. Abstract The article mainly explores the Hopf bifurcation of a kind of nonlinear system with Gaussian white noise excitation and bounded random parameter.
