热源运动的控制与仿真

Control and Simulation of Moving Heat Sources

为研究热源运动对热力系统性能的影响,需要给出热源在平面上的某一有限区域沿着运动轨迹进行移动时,控制热源运动状况的简化算法。物体的受热状态可用二维热传导方程描述,为求解这些方程,可用置换的方法进行简化,并利用分布式运动控制的算法予以实现。这些方法和算法都适用于二维对象,文章对热源平面移动时的运动控制算法进行了具体的设定和推导,并通过具体例子说明该算法的计算机实现过程与仿真方法。仿真结果表明,这些算法和方法是可行的、有效的。

In order to research the effects of moving heat sources on the heat power system,a computing moving controls when a heating source is moving along a path which stays in a limited area in a plane has been stated. The process state is described by two heat conductivity equations. The problem is solved by substitution and by distributed control of mobility. These methods are extended to two dimensional processes. Cases are reported of computing mobile controls in a plane. After simulation, results show that the algorithm and method are feasible and effective.
