摘要 中央空调系统是一个串联型动态系统,适合分解为若干子系统进行串联计算。为了求解中央空调大系统运行能耗的整体最优,通过对空调系统运行特性及模型的分析与能耗最小化计算模型的讨论,将大系统处理为最优控制的二次型凸问题,并把Lagrange对偶函数法运用于分解后的二级系统,得到整体系统的全局最优解,同时对算法进行了理论证明。 The central air-conditioning system is a series form of dynamical system, it can be is decomposited into many sub-systems for series computation. In the light of solving energy consumption overall optimal, the system may be treated as a quadric form convex problem, and so the Lagrange dual function method is applied to decomposited two-level system, and obtain overall system global optimal solutions. At the same time it carry on theory proof in regard to algorithm.
