Data-driven functional state estimation of complex networks
Yuan Zhang, Ziyuan Luo, Wenxuan Xu +8
The internal state of a dynamical system, a set of variables that defines its evolving configuration, is often hidden and cannot be fully measured, posing a central challenge for r…
A Note on Structural Controllability and Observability Indices
Yuan Zhang, Ranbo Cheng, Ziyuan Luo +1
In this note, we investigate the structural controllability and observability indices of structured systems. We provide counter-examples showing that an existing graph-theoretic ch…
Minimal Sensor Placement for Generic State and Unknown Input Observability
Ranbo Cheng, Yuan Zhang, Amin MD Al +1
This paper addresses the problem of selecting the minimum number of dedicated sensors to achieve observability in the presence of unknown inputs, namely, the state and input observ…
Observability Blocking for Functional Privacy of Linear Dynamic Networks
Yuan Zhang, Ranbo Cheng, Yuanqing Xia
This paper addresses the problem of determining the minimum set of state variables in a network that need to be blocked from direct measurements in order to protect functional priv…
