坦克行进间炮耳轴倾斜角预测模型研究
Prediction Model Research of Inclined Angle of Tank Gun Trunnion on the Move
摘要
Abstract
Focused on oscillatory data of inclined angle of the tank gun trunnion on the move,an modified grey prediction model is proposed. Firstly,the original sequence is transformed into positive and monotonic one to match modeling requirements of grey model by a new method of data transformation. Secondly,the traditional model background value is replaced by sum of area of rectangles in short intervals,while based on the criterion of unbiasedness,the relationship between the parameter of the reconstructed background value and modeling parameters is studied. Then a direct expression of the parameter of background value is put forward. Finally,the improved grey differential equation is constructed and hence an optimized prediction formula is shown. Through example analysis,the average relative error of prediction results of the modified model is 3.53 豫,which indicates a fact that the modified model is able to accurately predict changes of inclined angle of the gun trunnion.关键词
