conditions for describing the stability interval and emergence of Hopf bifurcation are obtained. Further, the Pyragas type delayed feedback control is used to delay the onset of Hopf bifurcation by increasing the gain and changing the fractional-order. Numerical examples show that the stability of ...
From Wikipedia, the free encyclopedia (Redirected from Andronov-Hopf bifurcation )Jump to: navigation , search In the mathematical theory of bifurcations , a Hopf or Poincaré–Andronov–Hopf bifurcation, named after Henri Poincaré, Eberhard Hopf , and Aleksandr Andronov , is a local bifurcation...
with smooth coefficient functions a and b such that a(x, λ) > 0 and b(x, λ, 0, 0, 0, 0) = 0 for all x and λ. We state conditions ensuring Hopf bifurcation, i.e., existence, local unique- ness (up to time shifts), regularity (with respect to t and x) and smooth ...
