基于一种新的鲁棒目标函数的化工过程数据校正

摘要

A new robust objective function-based data reconciliation method was proposed. The objective function properties and its influence function were analyzed to show a stronger robust of the proposed method;a linear and a nonlinear chemical process were simulated and compared with Huber method and Fair method,respectively.%给出了一种基于新鲁棒目标函数的数据校正方法,分析了目标函数的性质及其影响函数,表明了该方法对显著误差具有较强的鲁棒性.对一个线性和非线性化工过程进行了仿真研究,并与常用的Huber鲁棒估计法和Fair鲁棒估计法进行了对比分析.
