HOYOS VELASCO, Fredy Edimer; CASANOVA TRUJILLO, Simeón  and  VERGARA PEREZ, Darío Del Cristo. Dynamics of a Boost Converter with Inclusion of Internal Resistance Controlled with ZAD. Energética [online]. 2016, vol.37, n.2, pp. 144-153. ISSN 1815-5901.

As power electronic devices we highlighted the boost and buck converters, each with its respective configuration and power electronics applications. The mathematical model of the boost converter is represented by systems of differential equations piecewise smooth but with discontinuities at some points, thus generating very complex behaviors as quasi-periodicity and chaos when this is controlled. This article proposes a new model for a DC-DC boost converter in which parasitic resistances are included. Then the converter is controlled using non-linear and quasi-sliding ZAD control. Numerical simulations in Matlab show the presence of bifurcations and chaotic behavior. Through Lyapunov exponents it is determines the interval where there is presence of chaos. Then the system is controlled with FPIC to reduce and stabilize chaos, this is evidenced by bifurcation diagrams for voltage and current

Keywords : Flip bifurcation; chaos; non-linear sliding control ZAD; boost converter; PWMC; FPIC.
