Abstract

Piezostack-based active mounts have shown great efficiency for vibration control in a wide frequency range. In this paper, we investigate the performances of the global semi-active control strategy presented by Ichchou et al. [1] for a control system consisting of an active mount and a supported mass. The control strategy allows extracting vibrations energy of the supported mass, storing it in accumulators to be reused for powering in part the actuators (two piezostacks). Consequently, energy needs are reduced versus good control performances comparable to those of the active control based on the negative velocity feedback. The performances of the controller are evaluated in both frequency (transmitted force) and time (acceleration) domains which show that vibrations of the supported mass due to base excitations are efficiently attenuated with the proposed law. An energetic analysis confirms the reduced energy requirement compared to the active scheme.
