Abstract
It is known that a Lyapunov-based controlled boost converter has a globally asymptotically stable equilibrium point for known loads. However, in the case that the nominal load differs from the actual one, that unique equilibrium point bifurcates to three equilibria. The dynamics of this system is analysed here, as well as the local dynamics of the system extension resulting from the addition of an output error integral term.
