简介:没有已知的州的方程,新州的评价策略被设计对为电子的恶意的攻击是物理系统。由数据重建的想法启发了,(CS)压缩察觉到基于系统状态的Markov图在察觉和鉴定计划以后被用于剩余大小的重建,它对欺骗攻击增加州的评价策略的跳回。首先,observability分析被介绍从攻击决定测量重建和损坏水平的被触发的时间。特别地,学习的字典被建议由K单个的值分解(K-SVD)形成过去完成的字典,它根据测量数据的特征适应地被生产。由于剩余大小的不规则,另外,一个采样矩阵作为测量矩阵被设计。最后,模拟实验在6公共汽车力量系统上被执行。大小的重建被建议重建方法完成很好的结果表演,和相应效果分别地基于联合字典和传统的高斯或Bernoulli随机的矩阵比重建计划好。特别,当仅仅29%可得到的干净大小是左的时,建议策略的性能仍然是非凡的,它为五种恢复算法反映概论。
