Study on vibration control system of structures based on magnetic levitation technology

Abstract

This study expresses a novel active vibration control method for structures by using magnetic levitation (MA-GLEV) technologies. When a vibration occurs, a developed MAGLEV device will repeat to levitate and contact to the ceiling of structures properly. According to this movement, frictional force will be generated to consume vibration energy by the friction mechanism of the MAGLEV device. For making the MAGLEV device levitate stably, sliding model control method is employed. By varying levitation distance of the MAGLEV device, normal force which is related to friction can be adjusted. The experimental results show the effect of normal force on vibration control of structures, and verify the effectiveness of the proposed active vibration control method.
