【摘要】 通过对观测结构的研究探讨了观测的基本机理;提出了观测结构的6种形态,从根本上分析了病态性存在的原因。利用观测矩阵的QR分解结果,将对观测结构的分析过渡到对上三角矩阵的分析与计算。由此对观测结构进行了深入分析与度量,能够对观测结构的各种形态进行推断,进而对系统的Ⅰ类及Ⅱ类病态性作出推断与估计。更多还原

【Abstract】 According to the research of observation structure,the basic mechanism of observation has been discussed,six shapes of observation structure been brought forward,and the reason why the ill-conditioning exists been analysised from foundation.Making use of the result of QR decomposition,it can transit the diagnosis of observation structure into the analysis and calculation of upper triangular matrix,so that the observation structure can be analysised and measured deeply.The deduction on the various shapes from observation structure can also be carried out,then deduction and estimation can be made to systemⅠill-conditioning and Ⅱ ill-conditioning.更多还原
