Structural Controllability of Polysystems via Directed Hypergraph Representation

This document explores structural controllability of polynomial dynamical systems or polysystems. We extend Lin’s concept of structural controllability for linear systems, offering hypergraph-theoretic methods to rapidly assess strong controllability. Our main result establishes that a polysytem is structurally controllable when its hypergraph representation contains no hyperedge dilation and no inaccessible vertices. We propose two efficient, scalable algorithms to validate these conditions.
