Abstract

The vibration control system is widely used to suppress vibrations either locally for flexible structures or globally for rigid structures in various fields, such as civil engineering, automotive industry, aircraft industry and watercraft industry. As a conventional approach, passive vibration control gains compliments for its simplicity and ease of implementation, however, the limitation of inadaptability makes it fail to satisfy advanced requirements. Considering the fact many practical systems own time-varying vibration sources or wide vibration bandwidth, active control is an ideal strategy for great vibration control performance, but it has disadvantages such as power requirement, cost and complexity. Because of the combination of the versatility of active control and reliability of passive control, semi-active (adaptive-passive) vibration control has attracted considerable intention over the past decades. Semi-active vibration control systems can adjust their resonance frequencies without consuming extra energy in real time, therefore it has potential in engineering applications where high level of vibration control is required.
