Abstract

An integrated active-passive control for structural and electrical coupled systems is presented to achieve an effective vibration attenuation of vibrating structures. The transition of relative phase between displacement and voltage is focused on. The cooperative combined system is composed of both tuned electrical resonance and bang-bang active methods. Switching logics are devised for the integrated control based on the interactive relations between mechanical and electrical vibrations. Furthermore, this paper presents quite an interesting phenomenon, i.e., the relative phase-transition of electrical resonance in transient response, which cannot be found in steady-state condition. This phase-transition has been ignored in spite of an essential factor for integrated systems. Experiments on a 10-bay truss structure demonstrate that the integrated active-passive control enhances vibration attenuation of conventional bang-bang active systems.
