Parameter Identification of the Non-Linear Rolling Damping Based on PLS Regression Technique

Abstract:

The rolling motion analysis of ships or other marine structures is of paramount importance. However, one of the thorniest issues in the analysis is the determination of roll damping. The main objective of this work is to apply the Partial Least-Squares regression into the Bass Energy Method and Roberts Method, which are used for the identification of non-linear roll damping parameters. When the number of sample points decreases due to limitations of the experimental conditions and other factors, the differences between the results obtained from Partial Least-Squares Regression and from traditional Least-Squares method demonstrate the applicability of the proposed method.
