嵌入式系统最优能耗敏捷管理技术是解决广泛应用下系统能耗制约的关键。传统的系统能耗敏捷管理方法采用基于双基准态稳定下的判决思想，对固定的稳态和固定的非稳态进行低阶扩散研究，受限于低阶扩散特性对于系统高阶风险管理的片面性，无法实现最优敏捷管理。提出一种基于亚稳态高阶扩散模糊决策的最优嵌入式系统能耗敏捷管理设计，采用亚稳态下的高阶扩散特性，对嵌入式系统亚稳态下的实际特性进行描述分析，采用亚稳态描述符判断中间量，然后基于模糊决策思想，对亚稳态高阶扩散进行模糊向量积分，得到模糊决策，并将模糊决策结果应用于能耗管理，实现最优能耗敏捷管理。最后采用实际的嵌入式系统进行最优化系统能耗敏捷管理测试实验，结果表明，该方法的嵌入式系统在各种风险态下的能耗管理均优于传统方法，能耗平均节约37%，对于系统能耗管理具有很好的指导意义。

The agile optimal system energy management technology is the key of solving the system wide energy constrained applications. In traditional management approach systems, the energy agile thinking of dual judgment under steady-state benchmark for fixed steady and unsteady fixed low-level diffusion studies is used, the low-level diffusion characteristics is limited for high-level risk management system sidedness, it cannot achieve optimal agile management. An optimal system energy agile management based on fuzzy decision of metastable high-level diffusion method is proposed, the high-order dif-fusion properties of metastable under the actual characteristics is used, the fuzzy decision result is applied to energy man-agement and the agile optimal energy management is achieved. Finally, the actual embedded system is used to optimize en-ergy consumption data management agility test experiments, the results show that with the proposed method, the system power management state is better than the traditional method in various risks, the average energy savings is improved by 37%, and it has a good guidance for the system consumption management.
