摘要

不确定水质模型研究是提高和认识水环境中各种不确定性因素常用的手段

目前水质不确定模型主要是增加一个外部观测量

通过对观测结果的回归分析或滤波来分析不确定性因素的影响.本文将神经网络内嵌到水质模型中

从模型内部感知各种不确定性因素的变化

提高模型预测精度

丰富了不确定性水质模型研究内容.

Abstract

Research on uncertain water quality model is done to improve the knowledge of the uncertain water condition

and an externally observed variable is always used to analyse the effect of uncertain conditions by regression or filter analysis.A neural network is embedded in to the water quality model to perceive the uncertain conditions of water environment

which will improve the precision of water quality forecast and enrich the uncertain water quality model.
