A fuzzy predictive control scheme is proposed in dynamic positioning and a fuzzy predictive controller was designed base on the study of dynamic ship positioning. First, in the predictive control part, the designs of predictive model and correcting on line of predictive control are discussed. In the fuzzy control part, membership functions and fuzzy rules of fuzzy control are discussed. Evaluation of the algorithms and fuzzy predictive controller is made with project date. Simulation＇results show that the fuzzy predictive controller can hold the position and heading effectively.
