摘要
从反问题的角度出发 ,提出组合单元法求解水网地区水质特性的稀疏矩阵解法 ,在此基础上给出无约束污染物边界浓度及污染源项一类反问题的提法及相应的最优控制求解方法 .该方法避免了常规方法的试错求解过程及不确定性 。
From the view point of inverse problems,the integrated element method is introduced to solve the sparse matrixes of water quality characteristics for river network regions.The inverse problem without any constraint condition on the boundary concentration of pollutants and pollutant source is proposed,and a related solving method of optimal control is presented.The method can help avoid the trial and error process and indeterminacy of the conventional method,and the accuracy can be improved.
