Smart Electromagnetic Inerter-Based Vibration Absorber With Active Control for Enhanced Stability
Abstract The design of mechanical inerter-based vibration absorbers faces major challenges, particularly in accurately measuring the relative acceleration between the structure and the absorber. This article presents a novel solution to this issue using active control techniques. By utilizing a voice coil as a sensor, the relative velocity is captured and differentiated to estimate the relative acceleration. Two additional voice coils act as actuators, creating the inertance effect. The close placement of these actuators and sensors enables collocated feedback, ensuring unconditional stability. Experimental and simulation studies validate this innovative smart system through a ground-based absorber, showcasing two scenarios: (1) pure inertance feedback and (2) feedback laws that combine stiffness, damping, and inertance to boost performance. The results confirm superior stability compared to conventional methods, underlining the effectiveness of this smart device in vibration control.
