心脏搏动模型的Hopf分岔
Hopf bifurcation to models of reactions of human heart
摘要
Abstract
In order to understand the complicated dynamics of cardiac autonomic activity , the Hopf bifurcation to models of reactions of human heart under the action of external force and parametric noise is investigated in detail and deeply . First , the conditions of the existence of Hopf bifurcation to system are obtained . Second , the direction of Hopf bifurcation , the stability of bifurcating period solutions and the expression of the bifurcating periodic solution are rigorous derived and studied by means of complex normal form theory . Finally , numerical simulations are performed to justify theoretical analysis .关键词
