摘要: 南京烷基苯厂再沸油加热炉(F-501炉)系一多变量工业对象.本文描述了采用Rosenbrock 的逆奈氏阵列法进行解耦设计以及采用多变量Smith预估技术补偿对象纯之后所获结果,也 简要提到微机控制系统硬、软件的构成与特点.该系统投运一年多表明,控制性能完全满足设 计要求,且带来十分显著的经济效益.Abstract: Nanking Linear Alkyl Benzene Factory's reboiler oil heater (F-501) is a multivariable industrial plant. This paper describes the results which was obtained by decoupling design with INA method putting forward ,by Rosenbrock and time delay compensation of plant using multivariable Smith perdictor technigue. The construct and feature of microcomputer control system are briefed as well. This system has operated for over a year, it indicates that control performance satisfies the design requirements fully, and has achieved significant economical benefit.
