摘要
文中针对不同回路具有不同时滞的多变量稳定过程,提出了一种多变量解耦内模控制设计及其常规PID转化应用方法。所设计的多变量内模控制器能使系统稳定解耦,所得到的闭环系统根据开环系统时滞来描述。该方法为精馏等化工装置的复杂控制系统提供了一种新的优化和先进控制方案。
The decoupling internal model control （IMC） was investigated for multivariable stable processes with different time delays. And this method was extended and applied to a conventional PID control of DCS equipment by IMC-PID transform. All the stabilizing IMC controllers and the resulted closed-loop systems were characterized in terms of the open-loop system＇s time delays. The method has an advantage of being simple and easy to realize for the optimization and APC control of a complex process system like a rectification.
