Abstract

We propose an innovative method of fuzzy-based adaptive multimodal vibration suppression for structures with imperfect structural data. Our adaptive control consists of fuzzy inference, MamdanVs methodology, and semi-active threshold control. We demonstrate it to be applicable to multimodal vibration suppression for vibrating structures. Our proposed control only requires the information of natural frequencies for the real-time feedback control. We carried out experiments of vibration suppression using our fuzzy-based and conventional threshold controls, and compared their suppression performances. The experiment indicates that the fuzzy-based control can adapt to conditions outside the assumed range of excitations. The proposed fiizzy-based threshold control displays good adaptability when faced with sudden changes in vibrations, and also displays high suppression performance.
