Abstract:To design an effective automatic control system of planing craft,a prediction model should be built to realize the real-time and precise prediction of its motion attitude.The applicability of using MGM(1,N) model to predict the planing motion attitude was analyzed.According to the characteristics of planing craft motion attitude data and real-time request of prediction,the recurrence formula was proposed to calculate MGM(1,N) model’s parameter matrix after a batch of data was acquired.Using this formula,the prediction accuracy can be greatly improved and the predicting time can be prolonged without the significant increase of computational complexity.The result of numerical simulation shows that it is feasible to use recursive batch MGM(1,N) model to predict the motion attitude of planing craft and the prediction accuracy is very high.
