摘　　要：医药、石油化工中的精馏是一个多变量生产过程,各变量间的关系非常复杂,耦合度高,文章分析了两输入/两输出精馏过程的耦合关系及数学模型,利用对角矩阵和前馈补偿解耦方法设计解耦网络,使原来处于耦合关联下的两个系统完全独立,达到精馏过程稳定运行。Distillation of petroleum chemical medicine was a multi variable process, the relationship among variables were complex, high coupling degree. The coupling relationship and mathematical model of two input/two output distillation process was analyzed. The diagonal matrix and the feed-forward decoupling design method of decoupling network was used to design the original in the two system coupling relation under the complete independence, in order to achieve stable operation of distillation process.
