基于区域性气候条件的建筑节能供热分时控制方法

我国区域性气候条件多变,不同地区可以采用不同的方式实现建筑供热,降低建筑能耗,因此,提出基于区域性气候条件的建筑节能供热分时控制方法。根据我国不同区域条件的供热能耗负荷,获取建筑能耗负荷比重;设计模糊自适应的PID控制器,将建筑的供热负荷值输入控制器中计算,依据控制器的输出结果,实现建筑节能供热的分时控制;建立不同的控制方案。实验结果表明,设计方法可将建筑供热能耗节能率提升5%~8.7%,节能效果显著。

Numerical Minimum Time Control to a Class of Singular Integro-Differential Equations

This study presents a numerical method for determining the minimum time required for the states of one class of integro-differential equations of the first kind to reach its attainable region by assuming the forcing terms of the equations as controls. These equations consist of integro-differential parts containing weakly singular kernels. The feasibility of the numerical method is demonstrated by comparing the minimum time and corresponding possible time by using extreme controls to reach the attainable region under different initial conditions.
