摘　　要：采用一阶时滞模型作为主蒸汽温度广义被控对象模型,设计基于模糊自适应内模控制的主蒸汽温度控制系统。在不同典型工况辨识得到不同对象模型参数,根据模型参数和模糊自适应规则自动整定控制器参数。对所设计的控制系统进行仿真和实际应用。结果表明,在外部扰动或模型不能准确匹配及不同工况运行时,此控制策略较传统串级PID控制和Smith预估控制具有更好的控制品质。In this paper, the first order lag model is used as the generalized object model of main steam temperature to design thefuzzy adaptive internal model control based main steam temperature control system. The parameters of the object model areidentified under different operation conditions. According to the model parameters and fuzzy adaptive rules, the controller parametersare adjusted automatically. The designed system is simulated and applied in a power plant as well. The results show that, comparedwith the conventional cascade PID controller and the Smith prediction control, the system has a better control quality when thesystem operates under load disturbances or with model parameter deviations as well as under different operation conditions.
