Abstract

In this paper, we describe the design and implementation of a state observer for power electronics converters, the dynamics of which can be described by a linear-switched state-space model. The observer is also described by a linear-switched state-space model, and for each particular subsystem, the observer essentially behaves as a Luenberger observer. As part of the design procedure, we provide sufficient conditions that guarantee the stability of the observer. In order to experimentally demonstrate its feasibility, the observer is implemented in a dedicated real-time processor architecture. We present experimental results that illustrate the observer behavior when used for state estimation in single-phase and two-phase boost converters.
