  In this work, the problem of switching control design for DC-DC boost
converter is considered, in the case of operation under uncertain equilibrium
condition arising due to perturbations in the input and load parameters.
Assuming that these uncertain parameters are generated via a known linear
exo-system, a parameter estimator is designed to update the equilibrium point
for the switching controller in real-time. In order to mitigate the noise
amplification problem associated with the designed parameter estimator, the
estimation error injection term is filtered via a set of first-order filters to
obtain the desired level of noise suppression in the final set of estimates. To
demonstrate the efficiency of the developed scheme, a realistic application
scenario of a DC charging station for electric vehicles is considered, with
photovoltaic array as the source and a battery connected at the load side.
