摘要

传统的解耦控制方法由于其过于依赖模型辨识等问题难以被实际应用，且存在成熟系统不宜进行控制器再设计等问题，此外，回路解耦控制的专家经验难以提取与传承。因此以等效传函理论为研究基础，提出了一种面向解耦问题的基于序列决策的PID参数整定方法，提取历史数据中经验丰富的操作人员的控制序列。在解决回路之间存在耦合而使控制效果不佳的问题的同时，使工程人员的PID参数整定经验数字化得以传承，辅助初级人员进行操作。最后将所提方法应用于Matlab和Aspen两个仿真平台的耦合回路系统，获得满意结果，并验证所提方法的有效性和正确性。

Abstract

Traditional decoupling control methods have difficulties in industrial applications as a result of heavily relying on model identification and in controller re-designing as a result of mature system. Besides

it is difficult to extract and inherit expert experience of loops' decoupling controls. Based on equivalent transfer function theory

sequence-decision PID parameter tuning method was developed

which control sequences of experienced operators were effectively extracted from historical data. When facing poor control performance due to loops' coupling

junior staff could operate from inheritance of digitalized PID parameter tuning experience of experienced engineers. Method effectiveness and accuracy were verified in two coupling circuit systems in Matlab and Aspen simulation platforms.
