针对现有可重构性评价方法未充分考虑实际约束、难以反映重构潜力分布的合理性及缺乏可靠性分析等缺陷,提出一种考虑重构潜力分布与可靠性影响的能量及时间受限系统可重构性评价方法.首先,基于能耗最优控制,确定故障系统的最大可恢复状态域并优化其可靠度;然后,根据期望重构能力分布,对状态空间进行坐标同等化,得到各向等重要度的同等重构空间;其次,基于该空间的可恢复状态域体积,设计可重构性评价指标,并以精细积分法进行求解;再次,从系统设计和运行监测两阶段出发,介绍该指标的应用方式;最后,通过数值仿真,验证了所提方法的有效性,仿真结果表明,可重构性受时空因素的双重影响.
In view of the fact that the existing reconfigurability evaluation methods do not fully consider the practical constraints, it is difficult to reflect the rationality of the distribution of the reconfiguration potentials and the lack of reliability analysis, a new method is proposed to limit the energy and time of the reconfiguration potential distribution and reliability System reconfigurability evaluation method.Firstly, based on the optimal control of energy consumption, the maximum recoverable state domain of the fault system is determined and its reliability is optimized. Then, based on the expected reconfiguration capability distribution, the coordinate of the state space is equalized, Secondly, based on the volume of the recoverable state domain of the space, the reconfigurable evaluation index is designed and solved by the precise integral method. Thirdly, from the two stages of system design and operation monitoring Finally, the effectiveness of the proposed method is verified by numerical simulation. The simulation results show that the reconfigurability is affected by both the spatial and temporal factors.
