Abstract

In this work, two different mounts fabricated from two different smart materials are proposed for the vibration control of a flexible structure subjected to external disturbances. A semi-active magneto-rheological(MR) mount is firstly devised and its damping force controllability by the current intensity is evaluated. Subsequently, an active piezoceramic mount is devised and its field-dependent inertial force is experimentally evaluated. Each mount is then installed on the flexible structure and the corresponding control model is established. The LQG controller is designed for each mount system and empirically realized. Control responses of each control system such as acceleration and displacement are investigated in the frequency domain.
