On the Nonlinear Observability of Polynomial Dynamical Systems
Keywords:Nonlinear systems, observability, ideals, varieties
Controllability and observability are important system properties in control theory. These properties cannot be easily checked for general nonlinear systems. This paper addresses the local and global observability as well as the decomposition with respect to observability of polynomial dynamical systems embedded in a higher-dimensional state-space. These criteria are applied on some example system.
