Abstract

The piecewise linear mathematical model of the current-mode-controlled Buck-Boost (CMCBB) converter in continuous current mode (CCM) is established. By changing the value of reference current in the circuit and using bifurcation diagram, the path of the system to chaos through period-doubling bifurcation is revealed. In this paper, a cubic variance negative feedback chaos controller (CVNFCC) is introduced to guide the chaotic motion to the period-1 orbit successfully. Compared with the resonant parametric perturbation chaotic controller (RPPCC), it is proved that the chaotic controller is simple in design and easy to implement. In addition, the influence of the external coefficient H of the CVNFCC on the chaos control effect is deeply studied in this paper. Different external coefficients are selected for analysis. According to the analysis results, it is concluded that the larger the external coefficient is, the better the effect of chaos control is.
