Complex Dynamics and Hard Limiter Control of a Fractional-Order Buck-Boost System

Chaos and control analysis for the fractional-order nonlinear circuits is a recent hot topic. In this study, model deduced from Buck-Boost converter, its discrete solution obtained based on Adomian decomposition method (ADM). Chaotic dynamic characteristics of system are investigated by bifurcation diagram, 0-1 test, spectral entropy (SE) algorithm, NIST test. Meanwhile, discussed through two different ways, namely, intensity feedback hard limiter control. Specifically, can be realized using current in circuit, where device applied to branch current. The results show that proposed has complex behaviors potential application values engineering field.
