Hopf bifurcation control of the Qi 3-D four wing chaotic system via washout filter

This paper is concerned with the hopf bifurcation control of the Qi 3-D four wing chaotic system. Firstly, the stability of the origin of the system is studied, and the critical value of the system parameter at which hopf bifurcation occurs is investigated. Secondly, washout filter-aided feedback controller is designed for ensuring the stability of the bifurcated limit cycles. Finally, computer simulation results are presented to illustrate the analytical results found.
