摘　　要：竖炉焙烧过程的工艺指标难于在线测量且与控制回路输出间的动态特性具有非线性、强耦合、难以用精确模型描述、随生产边界条件变化的综合复杂性.为解决其优化操作运行与控制问题,建立了具有开放性和模块化的焙烧过程优化操作运行与控制半实物仿真实验平台.该平台采用优化运行层和常规控制层两层结构组成的操作运行与控制策略来设计开发.主要由优化运行系统、过程监控系统、PLC控制系统、虚拟执行机构与检测装置和对象模拟计算机系统组成.该平台实现各个系统的无缝集成,其过程信号与工业现场一致,实验结果表明了其有效性.Determining the technological indices of the roasting process in shaft furnace is difficult in not only the online measurement but also the modeling of their nonlinear and strong-coupling dynamic behavior in relation to the outputs from control loops to describe exactly the complexity that the process in varying with boundary conditions. To solve the problems of optimal operation/ control of the roasting process in shaft furnace, a hardware-in-loop simulation （HILS） platform is developed with openess and modularity. It adopts the optimal operation/control strategy which is a two layered structure, i.e. the optimal operation layer and conventional control layer. The modules of the platform include mainly the optimal operation system, process monitoring system, programmable logic controller （PLC）, virtual instruments and actuators, virtual plant system. Seamless integration features all the modules and their communication signals consist with in-site actual ones. Experiment results show the effectiveness of the platform.
