Abstract (EN):
Multi-input/multi-output fuzzy logic¿based controllers allow the inclusion of
di¿erent types of knowledge about the controlled process. The application of multivariable fuzzy controllers in a real process is di cult due to prac tical
limitations. This paper desc ribes an approach to the implementation of a MIMO
fuzzy hierarchical controller in a real process. Introducing a loop struc ture for
the fuzzy controller, the approach is based on a mixed decomposition method
and a hierarchical struc ture. The approach allows an important reduction in
a global fuzzy re lation needed to control the process under consideration¿ the
parallel operation of uninterruptible power supplies. The process multivariable
and nonlinear charac teristics make it an appropriate one to te st the presented method. Generalized simulation re sults are presented based on the proposed
approach. The comparative experimental results presented show the validity of
the method.
