In order to minimize the harm caused by the instability of a planing craft,a motion prediction model is essential.This paper analyzed the feasibility of using an MGM(1,N) model in grey system theory to predict planing craft motion and carried out the numerical simulation experiment.According to the characteristics of planing craft motion,a recurrence formula was proposed of the parameter matrix of an MGM(I,N) model.Using this formula,data can be updated in real-time without increasing computational complexity significantly.The results of numerical simulation show that using an MGM( 1,N) model to predict planing motion is feasible and useful for prediction.So the method proposed in this study can reflect the planing craft motion mechanism successfully,and has rational and effective functions of forecasting and analyzing trends.
