Paper Abstract

A new structural vibration control concept, using piezoelectric materials shunted with real- time adaptable electrical networks, has been developed. The variable resistance and inductance in an external RL circuit are used as control inputs. Novel energy-based parametric control schemes are created to reduce the total system energy (the main structure mechanical energy plus the electrical-mechanical energy of the piezoelectric material and electrical circuit) while minimizing the energy flowing into the main structure. The performances of the controllers are examined through computer simulations on a beam example. It is shown that the structure energy level and vibration amplitude can be suppressed effectively.
