Abstract
A novel method of hybrid vibration suppression using piezoelectric materials is proposed. It combines bangbang active control and energy-recycling semi-active control. The hybrid method saves actively supplied energy and is thus a low energy-consumption vibration control. Its effectiveness in suppressing vibrations was proven in numerical simulations and experiments using a 10-bay truss structure. Moreover, an innovative method to prevent undesired control chattering is proposed to further save energy supplied from the external source.
