摘　　要：本文应用MATLAB作为可视化建模工具,把理论研究和工程上的实现有机结合在一起。本文在对200MW机组过热器动态特性进行分析的基础上,分析了现有过热汽温控制方案存在的不足,提出了一种带SMITH预估器的模糊汽温控制系统方案,仿真结果表明采用这种策略的控制系统具有良好的控制品质。This paper uses MATLAB as a visual modeling tool to combine the theoretical study with the realiza- tion in engineering. Analyses the dynamic mechanism of the super heater through 200MW boiler and discusses the shortcoming of existing control scheme about super steam temperature. Puts forward a kind of control scheme with Smith predictor and fuzzy control. Result of simulation indicates this control system has good quality.
