摘要: 本文应用Bristol的相对增益概念,对具有非线性多变量和相关多回路的复杂蒸馏过程,建立起5×5调节和被调参数对的相对增益计算方法,以研究它在设计中的控制策略问题.该方法改进了2×2相对增益子集分析方法的不足,达到了比通常应用的方法更准确和全面地反映出控制回路间存在的相关作用的目的,从而找到在全局意义下的控制策略.

Abstract: On the basis of the concept of relative gain proposed by Bristol, we set up a new approach which can be used to analyze the interactions among distillation control loops so as to choose the loops which have the least interactions as an alternative optimal control mode. The newly developed approach is more rigorous and accurate than those subset methods and can determine the control mode for a distillation column at a total set scope.
