摘　　要：针对工业生产中常见的加热炉装置,设计了基于西门子公司PCS7过程控制系统的控制方案。为了保证物料出口温度、烟气含氧量和物料流量达到需要,采用了比值-串级控制系统、前馈控制系统和史密斯滞后补偿器。同时为了达到节能的目的,引入变频调速技术调节物料和燃料的流量。控制过程采用高级多功能过程实训系统仿真加热妒,利用PCS7控制系统实施控制方案并利用上位机软件进行在线的实时监控。Aiming at the commonly-used heating furnace in industry , the PCS7 control system-based control scheme was designed for it , in which, the ratio-cascade control system , the feedforward control system , the feedback control system and Smith lag compensator employed can ensure materials ’ outlet temperature , flue oxygen content and the materials flow;and the frequency conversion technology applied can realize energy con-servation through regulating both materials and fuel flow;and the system with advanced multifunction process training system can simulate the heating furnace and PCS 7 control system can implement both control strategy and online real-time monitoring through PC monitor software .
