摘要

This paper is concerned with the Hopf bifurcation control of a modified Pan-like chaotic system.Based on the Routh-Hurwtiz theory and high-dimensional Hopf bifurcation theory,the existence and stability of the Hopf bifurcation depending on selected values of the system parameters are studied.The region of the stability for the Hopf bifurcation is investigated.By the hybrid control method,a nonlinear controller is designed for changing the Hopf bifurcation point and expanding the range of the stability.Discussions show that with the change of parameters of the controller,the Hopf bifurcation emerges at an expected location with predicted properties and the range of the Hopf bifurcation stability is expanded.Finally,numerical simulation is provided to confirm the analytic results.
