A Hybrid Regulation Method for Enhancing Chemical Oscillation Reaction Process

Abstract

The present invention provides a hybrid regulation and control method during the enhanced chemical oscillating reaction process. According to the method, firstly, a nonlinear dynamics differential rate equation for describing chemical properties is written based on a main reaction equation. Secondly, the rate equation is analyzed to find out chemical parameters for causing the oscillation of the system and then a corresponding bifurcation diagram is drawn. Finally, based on the hybrid regulation and control technology, the parameter interval for causing the oscillation of the system is expanded and the oscillation amplitude is increased. According to the technical scheme of the invention, on the basis that the original properties of the chemical oscillating reaction are maintained, the oscillating process is enhanced. Therefore, the oscillation amplitude and the oscillation interval are increased. As a result, the extraction of chemical substances and the research on the dynamics of non-linear chemical reactions are facilitated. The method has an important role in energy recovery and fuel regeneration. The method can be used for processing the chemical oscillation, and no artificial factor is required for processing weak signals. In this way, obtained signals are objective.

Description

technical field [0001] The invention belongs to the field of nonlinear chemistry and relates to a method for strengthening chemical oscillation reaction process. Background technique [0002] In general chemical reactions, the concentrations of reactants and products change monotonically, and finally reach an equilibrium state that does not change with time. However, in some reaction systems, the concentration of some components will fluctuate, showing periodic changes, this phenomenon is called chemical oscillation. Since the former Soviet scientists Belousov and Zhabotinskii discovered the oscillation phenomenon in chemical reactions in the 1960s and established the first model Oreganator model to describe this phenomenon in the 1970s, nonlinear phenomena appearing in chemical reaction systems such as multiple stationary states, Oscillations, chaos, and chemical waves have attracted widespread attention from scientists. Later, the scholars of Brussel School gave the famo...

However, this method only considers the weakening effect, which has a negative effect on fields such as chemical oscillation reactions.

The method proposed in the document "Hopf bifurcation control of congestion control model in a wireless access network" is to improve the fuzzy control method and apply it to the congestion model of the wireless access network to delay or eliminate the Hopf bifurcation that appears in the model. This method The fuzzy control method is similar to the fuzzy control method, but only changes the range of control parameters, without considering the important role of Hopf bifurcation strengthening on the dynamical system
