Abstract
In this paper a set of controllability and observability conditions are proposed for vibration control systems with viscoelastic damping. Both conditions are stated in terms of the eigenstructures (eigenvalues and eigenvectors) of the control systems under consideration. They are similar to the well known eigenvector tests, except that to determine controllability, the knowledge of the stress-strain relations of the viscoelastic damping material is needed in addition to the modal information.
