Adaptive Optimal PMU Placement Based on Empirical Observability Gramian
Junjian Qi, Kai Sun, Wei Kang
In this paper, we compare four measures of the empirical observability gramian, including the determinant, the trace, the minimum eigenvalue, and the condition number, which can be…

Partial Observability and its Consistency for PDEs
Wei Kang, Liang Xu, Francis X. Giraldo
In this paper, a quantitative measure of partial observability is defined for PDEs. The quantity is proved to be consistent if the PDE is approximated using well-posed approximatio…
