fuzzy state space model fuzzy dynamic fuzzy thresholding algorithm a thresh-
models in state space format. A typical ex- olding algorithm with a threshold selected
ample is a set of local linear state space mod- based on fuzzy measure.
els smoothly connected through a set of non-
linear membership functions. fuzzy tuning the tuning of a control sys-
tem using fuzzy logic and fuzzy rules.
fuzzy system a fuzzy system is a set of
IF-THEN rules that maps the input space, fuzzy union an operator that take the max-
say X, into the output space Y. Thus, the imum value of the membership grades.
fuzzy system approximates a given function
F : X → Y by covering the function’s graph FWHM See full width at half max.
with patches, where each patch corresponds
to an IF-THEN rule. The patches that over-
lap are averaged. See also fuzzy inference
