Active Vibration Control Prototyping in Ansys: A Verification Experiment

The paper demonstrates the possibility to use finite element analysis packages for the prototyping of control algorithms for active vibration control. A model of a laboratory demonstration device consisting of a clamped beam with piezoceramic actuators has been prepared in ANSYS. The free response of this system is compared to laboratory measurements to verify the validity of the base model. A simple linear quadratic (LQ) control system and a state observer have been implemented into the native parametric design language of ANSYS. The complex electro-mechanical transient response of the control system has been compared to laboratory measurements, verifying the validity of the proposed approach.
