A novel 3-D fuzzy logic controller design using table look-up scheme

Three-dimensional fuzzy logic controller (3-D FLC) is a novel FLC developed for spatially-distributed parameter systems. In this paper, we are concerned with data-based 3-D FLC design. A table look-up scheme is employed to design 3-D FLC in terms of input-out pairs. The design is composed of five steps, including division of data space, generation of fuzzy rules, degree assignment of rule, combination of fuzzy rule base, and fuzzy system integration. A catalytic packed-bed reactor is taken as an application to demonstrate the effectiveness of the 3-D FLC.
