Abstract
To achieve an effective vibration attenuation of vibrating structures, a novel integrated active-passive control is presented. The integrated method is composed of two approaches; tuned electrical resonance and bang-bang active. Based on the interactive relations between mechanical and electrical vibrations, switching logics are devised for the integrated control. The paper presents the relative phase-shift of electrical resonance in non-stationary excitation, which cannot be found in stationary excitation. This phase-shift has been ignored although it is an essential factor for integrated systems. We demonstrated that the integrated active-passive control enhances vibration attenuation of conventional bang-bang active systems by using experiments on a 10-bay truss structure.
