Abstract:
Chemical reactions with oscillating behavior can present a chaos state in specific conditions.
In this study, we analyzed the dynamic of the chaotic Belousov–Zhabotinsky (BZ) reaction using
the Györgyi–Field model in order to identify the conditions of the chaos behavior. We studied the
behavior of the reaction under different parameters that included both a low and high flux of chemical
species. We performed our analysis of the flow regime in the conditions of an open reaction system,
as this provides information about the behavior of the reaction over time. The proposed method for
determining the favorable conditions for obtaining the state of chaos is based on the time evolution
of the intermediate species and phase portraits. The synchronization of two Györgyi–Field systems
based on the adaptive feedback method of control is presented in this work. The transient time until
synchronization depends on the initial conditions of the two systems and on the strength of the
controllers. Among the areas of interest for possible applications of the control method described in
this paper, we can include identification of the reaction parameters and the extension to the other
chaotic systems.
