Abstract
This paper describes a new design method for a multiple-input multiple-output, multiple-mode, positive-positionfeedback control strategy suitable for providing effective vibration attenuations to non-ideal asymmetrical structures. A thin plate with three supporting feet is used to form a non-ideal one-plane asymmetrical structure that can mimic many real-life scenarios. The aim is to keep the structure vibration-free while the base of the structure is constantly disturbed. A new parameter-selection method that can acknowledge the asymmetrical behaviors of the system and provide a better damping performance is proposed. The design process incorporates optimization considerations, and guarantees the stability of the resulting closed-loop system. Real-time experimental results reveal that the proposed method can achieve up to > 20 dB (or 90%) vibration attenuations and further improve the damping performance of its existing counterpart by up to 26%.
