Paper Abstract

This paper presents new insights obtained from analyzing the active-passive hybrid piezoelectric network (APPN) concept. It is shown that the shunt circuit not only can provide passive damping, it can also enhance the active action authority if tuned correctly. Therefore, the integrated APPN design is more effective than a system with separated active and passive elements. However, it is also recognized that a systematic design/control method is needed to ensure that the passive and active actions are optimally synthesized. Such a method is presented. The bandwidth issue for the APPN configuration is also addressed.
