| Abstract |
This paper deals with the estimation problem in a
three-phase converter using a linear observer. In general, most of
the schemes used to control the three phase voltage source
converter assume the exact full state information provide by a set
of sensors. However, from a practical point of view, it is useful to
explore the possibility of reducing the number of sensors, or even
using the soft sensors as back up for security purposes. On the
basis of some structural properties of the converter, it can be
mathematically shown that it is possible to design such estimators.
In this light, a linear mathematical model observer with the
average dc current is proposed. Simulations and experiment
results are shown to demonstrate the performances of these soft
sensors. |
