Ship Flap-Fin Equivalence Analysis Based on AHP

In order to verify the similarity of the servo system of the main-fin and the flap-fin of the established fin-flap control physical simulation system in the drive way with the prototype system, the method of equivalence analysis based on the principle of similarity is proposed in this paper. In order to better determine the weights of each subsystem, the consistency correction method of the judgment matrix is studied combined with hierarchical analysis principle. Finally, the main-fin / flap-fin servo system is taken for example to analyze the equivalence of flap-fin control of physical simulation system, and the proposed method in this paper is proved to be feasible.
