Abstract

A structural control concept, using multiple active-passive hybrid actuators (piezoelectric materials with active voltage sources and external passive RL circuits) on a ring structure, is investigated. A method is developed to simultaneously optimize the active control gains and the values of the shunt resistors and inductors. Kalman filter is employed to estimate the states of this multi-input-multi-output systems. Analysis results indicate that the proposed approach can suppress vibration and noise radiation effectively, and it can achieve better performance with less control effort as compared to a purely active system.
