Chaos control and anti-control in Boost converter based on altering correlation

Abstract

Chaos control and anti-control are one pair of inverse problems. In this paper, the correlation of system state variables is investigated, and the method of realizing the chaos control and anti-control of system under the condition of variation of correlation coefficients of current controlled continuous current mode Boost converter is analyzed. The above these lay the theoretical foundation for practical applications. Discrete-time model of system is established. The mechanisms of chaos control and anti-control in Boost converter are theoretically explained by monodromy matrix theory. The research results indicate that only when the correlation coefficient of system is changed, the Boost converter can be controlled from any state to period 1, 2, 4 orbits or chaotic state, which means that the output of the system can realize chaos control and anti-control. Simulation results verify the analysis results.
