Abstract

EVIS is the first commercial active vibration control system suitable for general purpose application. It's design closely follows the guidelines and principles described by Sandercock in the previous paper. We First present quantitative operating data For the system, and then discuss some of the unique qualitative aspects of that performance. Some examples of specific applications which are particularly well suited for active control technology are discussed. We have found that the usual models for understanding the operation of conventional passive vibration control systems are not adequate when considering the corresponding active systems. Therefore we discuss a simplified model which has proved useful for estimating the operational benefits of active systems in actual applications.
