Abstract

Piezoelectric materials are finding increasing applications in active vibration control of structures. Modeling of a piezoelectric laminate, often results in an infinite-dimensional or a very high-order model. For control design purposes, such a model is simplified by removing higher frequency modes which lie out of the bandwidth of interest. Truncation can considerably perturb the in-bandwidth zeros of the truncated model. This paper suggests a method of minimizing the effect of the removed higher order modes on the low-frequency dynamics of the truncated model of a piezoelectric laminate beam by adding a zero frequency term to the low-order model of the structure. Simulations and experimental results are presented
