工程设计中,常常用到压缩因子,但由于需采用迭代计算,造成计算困难。采用PLC的功能块图编程语言,利用反馈变量方便地实现了迭代运算,解决了压缩因子的计算问题。
Engineering design, often use the compression factor, but due to the need to use iterative calculations, resulting in computational difficulties. Adopting the function block diagram programming language of PLC, the iterative computation is conveniently realized by using the feedback variable, and the computation of the compression factor is solved.
