本文介绍了相对增益的概念,详细推导了计算相对增益的方法,并用相对增益的概念分析了精馏塔两端产品成分调节系统的相关问题.介绍了根据过程增益对精馏塔实施静态去耦控制的方法,指出对静态去耦进行动态补偿可以改善系统的品质,并讨论了精馏塔的部分去耦控制.最后,介绍了当精馏塔的动态特性在可以求取的情况下使用的动态理想去耦和简化去耦控制.
This paper introduces the concept of relative gain, derives the method to calculate relative gain in detail, and uses the concept of relative gain to analyze the related problems of product ingredient adjustment system at both ends of rectification column.It is introduced that the static decoupling Control method, it is pointed out that the dynamic compensation of static decoupling can improve the quality of the system, and the partial decoupling control of the rectifying tower is discussed.Finally, the paper introduces the dynamic characteristics of the rectifying tower when its dynamic characteristics can be used Dynamic Ideal Decoupling and Simplified Decoupling Control.
