This paper presents a new control methodology
that enables a fuzzy controller to watch its output
and if necessary change the inference rules by iterative
steps. First, we present our simulation done with
a classic fuzzy logic controller model which uses the
max-min composition for the inference rule system
and calculates a singleton from the fuzzy set of the
output by means of the center of gravity method [8].
Second, we present a new fuzzy logic controller model
with a dynamic rule set (FCD). Finally, we discuss the
results of the simulation done with the new FCD and
compare them with those of the classic controller.
