INTEGRATED MODEL OF A FLEXIBLE BEAM WITH PIEZOELECTRIC PLATES FOR ACTIVE VIBRATION CONTROL

摘要

A new approach to the integrated modelling of a mechanical structure and piezoelectric plates is presented. In particular a beam-like structure is considered, i.e. a structure which may be modelled by means of the elastic line equations. It is shown how to include into the beam model the interaction with the piezoelectric sensors and actuators dynamics and with the dynamics of the electric network at which the piezoelectric devices are connected. The resulting model is particularly useful for the design of control systems.
