Active integral vibration control of elastic bodies

Abstract

This paper deals with the design and analysis of active integral vibration control of elastic beam using piezoactuator. The concept of integral control means that multiple distributed piezoapatches are controlled using one integral feedback signal. This concept has been verified by simulations. However, it was detected that the dual concept of integral sensing, i.e. to integrate the signals from multiple piezopatches as sensors, fails in the case of position feedback due to the mutual interaction of piezopatches as sensors and actuators.
