摘要
根据灰色系统白化插值生成理论和建模机理 ,分析动态测量中灰色模型插值的可行性。并将动态测量数据建立白化插值生成灰色模型 ,进行动态测量插值预测 ,验证其可行性。由于动态测量特性和灰色模型预测的局限性 ,对模型的测量准确度提出较高要求。因此 ,提出改进白化插值生成灰色模型 ,采用基于灰色递阶预测的动态插值生成方法 ,以保证长期预测插值的动态测量特性。
According to the theory of whitening the interpolation and the principle of the model setting. The feasibility of the dynamic measuring interpolation Grey Model is analysed. The paper also discusses and proves the feasibility of setting up the whitening of the interpolation Grey Model according to the data of the dynamic measurement, and the evaluation of the dynamic measurement data. Due to the limitation of the characteristics of the dynamic measurement and the Grey Model's evaluation, the higher model accuracy is required. Based on Grey Model of the whitening interpolation, using the method of the Grey increasing order evaluation's dynamic interpolation to insure the characteristics of the long term's dynamic interpolated measuring data is gived.
