Abstract

This paper focuses on various vibration suppression schemes for Active Composite Struts (ACS) and Active Composite Panels (ACP). Dynamic responses of struts and panels using piezoelectric sensors and actuators were analyzed and evaluated by the finite element method. Four different vibration suppression schemes for ACS and ACP have been studied. Objectives were to first investigate various schemes for active vibration suppression that can be determined directly without trial and error, and Second to determine a scheme that can completely suppress the vibration and is easy to use. Four schemes were considered, namely, 1) constant voltage (CV), 2) optimum voltage (OV), 3) corresponding voltage (COV) and 4) truncated corresponding voltage (TCOV) schemes. This paper also discusses the pros and cons of each and provides guidelines for active vibration suppression of intelligent structures.
