对强迫冷却过程冷却流体质量最小化进行重新分析。指出并分析已有文献中建立的强迫冷却过程模型存在的一些问题,建立了精确的模型,给出了冷却流体质量最小最优控制问题表述。由于基于精确模型的最优控制问题求解困难,所以简化并建立了一个近似模型,利用最优控制理论得到冷却流体质量最小时的强迫冷却过程最优构型,并与原有模型下的最优构型进行了比较。 Re-analyze the minimization of cooling fluid quality during forced cooling. Some problems existing in the forced cooling process model established in the existing literatures are pointed out and analyzed. An accurate model is established and the expression of the minimum and optimal quality control of the cooling fluid is given. Due to the difficulty of solving the optimal control problem based on the exact model, an approximate model is simplified and established. The optimal configuration of the forced cooling process is obtained by using the optimal control theory and compared with the optimal model Configurations were compared.
