Primary Research on the System Identification Method of Pitching Motion of Composite Trimaran
Abstract: The method of system identification has been initially applied in the field of the shipbuilding, especially in the application of the ship maneuverability.This article established the mathematical model of system identification of composite trimaran pitching motion model based on the genetic optimization algorithm, using VB language to write the recognition software, Design and produce a composite trimaran test model, doing the free pitching decay test ,then completing the pitching motion system identification according to the test data, and got the pitching motion equation which will be used to do the forecast ,the results of forecast can well match with the test results,confirmed the feasibility of this set of identification method, laid the foundation for other sway motion research of composite trimaran.
