Abstract
This work investigates the state feedback control of certain DC-DC power converters. As a first step,
the models of the considered converters are established; their properties are analyzed in both dynamic
and static regimes. As a second step, the linear state feedback, based on the poles placement, is
designed and tested on the modelled DC-DC converters. For the case of unavailable states, a linear full
order observer is introduced to estimate the missing variables. As a third step, the passivity based
control (PBC) is considered. The PBC exploits the energetic structure of the DC-DC converters to
achieve the desired performance. Also, a passivity based observer is introduced to estimate the
unmeasured variables. The simulations tests were conducted in the PSIM software environment. The
obtained results were effective and confirm the theoretical predictions.
