酒精精馏塔的模糊解耦控制

Fuzzy Decoupling Control of Alcohol Distillation Column

针对酒精精馏过程中精馏塔塔顶和塔底2个温度控制回路存在较强耦合,提出一种酒精精馏塔模糊解耦控制器的设计和实现方法,并应用于筛板式酒精精馏塔实验装置。试验结果表明,此控制系统实现了解耦控制的要求,与常规的2个独立PID回路控制相比较,在产品质量和节约能耗方面都具有较大的优势。

A design and implementation method of a fuzzy decoupling controller of an alcohol distillation column is introduced, which applied to a sieve plate alcohol distillation column experimental device according to the temperature control loops of the column top and the column bottom have strong coupling in the alcohol distillation process. The experiment result shows that the control system can realize the demand of decoupling control. It has great advantages in product quality and energy consumption reducing by comparing with the conventional double independent PID loops.
