大型嵌入式设备运行能耗在线控制仿真

Simulation of on Line Energy Consumption Control for Large Scale Embedded Equipment

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。

This article proposes an online control method for operation energy consumption of large-scale embed- ded device. An objective function of the online control is built, then kinetic equation is used and the minimum princi- ple is introduced to build Hamihonian function corresponding to the minimum energy consumption model. The opera- tion 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.
