摘要
阐述了炉子最优控制中确定目标函数的困难,在于炉膛换热在模型中被充分简化,从而使真实目标与保留参量脱耦.提出以炉膛和被加热金属两部分的简化能量平衡式构成目标函数,并以变分法导出可求目标极值的微分方程.
he difficulty in determining the objective function of optimal control of furnaces mainly lies inthe full simplification that is necessary for heat exchange within the chamber -- thus making the real objective variables decoupled with reserved para.meters. This paper presents a proposal to the objective function that forms the way the energy equilibrium equations for heat exchange in furnace chamber and heat conduc tion in slab are both simplified. Further a partial differential equation is derived available to objective ex tremum by variational method.
