One-loop sensorless flatness-based method for a nonideal boost converter

Abstract

The article presents a controller for a boost converter using flatness-based control. The developed model is close to the actual physical system thanks to the proposed observer to estimate the state variables and losses. Proposed controller can control both inductor current and output voltage in a one-loop structure, so there is no limitation on the system's bandwidth compared to the cascaded control. Simulation results are presented to validate the proposed method.
