粒子加速器局部控制网形变分析

基于泰勒展开的方法实现局部控制网的拟合，使用卡方检验判断局部控制网中是否存在形变点。若存在形变点，则在选权迭代的过程中找到局部控制网中所有的形变点，并将卡方检验通过作为迭代终止条件。对哈尔滨工业大学空间地面模拟装置2号终端控制网的两期观测成果进行了分析，实验表明，将卡方检验和选权迭代法加入控制网拟合之后，可以很好地探测出局部控制网中的形变点。在找出所有形变点之后，可以求得更为准确的局部控制网拟合参数。

Analysis on deformation of partial control network of particle accelerator

The fitting of the local control network is realized based on the method of Taylor expansion, and the chi-square test is used to judge whether there is a deformation point in the local control network. If there are deformation points, find all the deformation points in the local control network in the process of weight selection iteration, repeat the above process until the chi-square test passes. The two-phase observation results of the Harbin Institute of Technology Space Environment Simulation and Research Infrastructure (SESRI) No.2 terminal control network are analyzed. The experiments show that after adding the chi-square test and the weight selection iteration method to the control network fitting, the deformation points in the local control network can be well detected. After finding all the deformation points, more accurate local control network fitting parameters can be obtained.
