大型嵌入式设备运行能耗在线控制仿真

摘要

This article proposes an online control method for operation energy consumption of large-scale embedded device.An objective function of the online control is built,then kinetic equation is used and the minimum principle is introduced to build Hamiltonian function corresponding to the minimum energy consumption model.The operation parameter of the large-scale embedded device is confirmed.Thus,the on-line control is achieved via simulating energy consumption state in the large-scale embedded device.Simulation results show that the method reduces energy consumption effectively during startup of the large-scale embedded device.%对大型嵌入式设备运行能耗控制问题的研究,能够有效改善大型嵌入式设备能源消耗过多现象.对嵌入式设备运行能耗的在线控制,需要建立最小能耗模型对应的哈密顿函数,确定大型嵌入式设备的运行参数.传统方法对设备运行能耗进行混杂动态建模,得到设备投切行为和变频行为,但忽略了获取设备运行参数,导致控制精度偏低.提出大型嵌入式设备运行能耗在线控制方法,通过建立大型嵌入式设备运行能耗在线控制的目标函数,利用动力学方程,并引入最小值原理,建立最小能耗模型对应的哈密顿函数,确定大型嵌入式设备的运行参数,通过模拟大型嵌入式设备中能量消耗状态,实现对大型嵌入式设备运行能耗的在线控制.实验结果表明,所提方法有效的降低了大型嵌入式设备启动过程的能耗.
