Data-Mining-Based Fuzzy Control Design for Marine Dynamic Positioning System of Ships

Abstract

Considering the dynamic positioning (DP) problem of a surface ship with unknown model dynamic parameters and unknown environmental disturbances, this paper develops a data-mining-based fuzzy control scheme. Under the certain operating and environmental conditions of a ship, the scientific and effective fuzzy rules for the DP of ships are extracted using the data-mining technique. Based on the extracted fuzzy rules, the DP fuzzy control law is designed. Finally, the simulation studies on a supply ship Northern Clipper are carried out to verify the effectiveness of the designed DP fuzzy control law.
