  In this paper, the eigenvalue embedding problem of the undamped piezoelectric
structure system with no-spillover (EEP-PS) is considered. It aims to update
the original system to a new undamped piezoelectric structure system, such that
some eigenpairs are replaced by newly given or measured ones, while the
remaining eigenpairs are kept unchanged. A set of parametric solutions to the
EEP-PS are provided and the performance of the proposed algorithms are
illustrated by numerical examples.
