An explicit Hopf bifurcation criterion of fractional-order systems with order 1 < α < 2
Abstract
A Hopf bifurcation criterion of fractional-order systems with order 1 < α < 2 is established in this paper, in which all conditions are explicitly expressed by parameters without solving the roots of the relevant characteristic polynomial of Hopf bifurcation conditions. It avoids the problem that existing methods may fail due to the computational complexity in the multi-parameter situation. The bifurcation hyper-surface of multi-parameter can be obtained directly.
