Reduced-dimension multilayer FLC based on rough set theory
Fang Wang, Gang Xie, Keming Xie · 2004
In this paper a new RST-based algorithm is introduced which extracts knowledge from field data and establishes fuzzy rules of reduced-dimension multilayer fuzzy controller. It is advantageous for understanding, checking rules and artificial correction to keep every level's fuzzy inference rules in three-dimension sizes. The rough-fuzzy controller is combined with conventional PID, building up the hybrid intelligent controller. The simulation of load control system shows that the hybrid controller processes higher control qualities with high speed, small overshoot and strong robustness.
