建立了模态可观性的系统理论概念与保证鲁棒信号恢复的指标之间的联系-稠密性和限制等距性。见解是来自分组信号，以确保保证恢复稀疏和虚假异常损坏的同步相量测量。信号分组上的命题进行了验证，从IEEE测试系统的模拟数据，以及从美国公用事业领域PMU测量。
A connection is established between the system-theoretic notion of modal observability, and the indices guaranteeing robust signal recovery– denseness and restricted isometry. Insights are derived for grouping signals to ensure guaranteed recovery of synchrophasor measurements corrupted with sparse and spurious anomalies. The propositions on signal grouping are validated on simulated data from a IEEE test system, as well as field PMU measurements from a US utility.
