PROII精馏塔sure算法Component Averaging Factor参数对 ...？

用默认的0算塔比较难收敛，但是改为3后收敛很快，不知道修改此值对计算结果是否有影响？ 个人理解流程收敛的话，那结果应该问题不大，有条件的话，可以用aspen做个比对或者对比现场数据。 根据提示，3应该是该值推荐的上限，既然没越界，说明还是可行~ component averaging factor (sure algorithm only): factor for computing the next set of trial compositions. a value of unity gives equal weight to the current and last set of compositions when they are averaged. a value of 2.0 gives double weight to the last set of compositions. values higher than 3.0 are not recommended.

明白了，谢谢各位大神帮忙，太有用了。

各位大神，在proii精馏塔sure算法中，convergence data中有一个参数component averaging factor，请问这个参数是什么意思？修改此参数对计算出来的结果有什么影响？会不会使计算结果不准确？请各位大神帮忙解答，谢谢啦。

这个是sure算法下的收敛辅助工具，有些类似于io算法里面的damping factor，而不是收敛精度要求，所以这个设置可能会增加迭代次数，但对收敛结果没有影响。下面是从帮助文件里面挖出来的原版信息，供您参考 component averaging factor : this weighting factor for update of compositions is used for the sure algorithm. a factor of 1.0 gives equal weight to the current and last set of compositions; a factor of 2.0 gives double weight to the last set of compositions, and so forth. a default value of 0.0 is supplied by pro/ii. further explanation： ...... the component averaging factor for sure columns is analogous to the damping factor for inside-out columns and may aid convergence of columns in which the overall error is oscillating close to a converged solution. the component averaging feature increases the number of iterations needed for column convergence.
