Analysis of the bifurcation diagram of a hybrid bistable system with feedback controls of chaos.
Based on the dynamic equation of a hybrid bistable system with a delayed feedback, we have studied changes of the bifurcation diagram of its output oscillation under chaos suppression and delayed feedback control of chaos, respectively, and the physical origin of these changes. The result clearly shows that, in this case, the input intensity of the system is replaced by a smaller effective input intensity. So the bifurcation diagram is shifted to its right side, and a certain part of the chaotic oscillation becomes periodic oscillation.
