【 摘 要 】

Due to the absence of power demands and yet effective performances, the semi-active tuned mass dampers (STMDs) have been broadly investigated. However, there is still a gap between the theoretical simulations and practical implementation of controlled tuned mass dampers. Moreover, using displacement and velocity sensors make such control systems less cost-effective, less reliable, and more complex. In this paper, the acceleration-based ground-hook semi-active control (ABGH) was proposed for an electromagnetic regenerative tuned mass damper (ERTMD). In this manner, a prototype of a compact back iron-based ERTMD was manufactured. The concept of a controllable system with switched transistor was utilized for the proposed ERTMD. Comparative simulations between the controlled and passive ERTMD was conducted and then validated by experimental results of the ERTMD prototype implemented in a protected mass test-bench similar to a typical vehicle unsprung mass. This paper concluded that the proposed control policy can be utilized for the ERTMD to increase the regenerative ability of the fabricated ERTMD under random excitations.
