Partial observability in structured bilinear systems using a graphical approach

This work is dedicated to the study of partial observability for structured bilinear systems using a graph-theoretic approach. The proposed method assumes only the knowledge of the system structure. The graphical condition for partial observability is given and if it is not satisfied then solutions of sensor placement are given in order to recover the system partial observability. This sensor placement is easy to determinate because it consists of finding paths on a digraph and computing indices.
