A Method of Multivariate Analysis in A Ceuracy Design of Engineering Control Network

This paper joins up with the method of main element analysis and the method of distorting mathematic model in modern designing of engineering control network, It puts forward multivariate analysis method in accuracy design of engineering control network based an spectral decomposition. In the article, the auther will introduce the fundamental principle of this method and illustrate its efficiency to judge the quality of control network designing with example.
