基于能量回收的土木工程结构振动控制

为了解决土木工程结构振动的主动和半主动控制技术对外界电源过分依赖的问题，系统回顾了基于能量回收与利用的各种结构振动控制系统。在此基础上，提出了一种自供电磁流变阻尼器减振系统，实现了振动控制的自供电与传感；指出了该系统的应用前景、亟待解决的问题和进一步的研究方向。研究结果表明：该系统既可以作为具有自适应特征的被动控制装置，也可以设计为半主动控制系统，同时该系统还可以和其他结构控制系统组合使用。

Structural Vibration Control Based on Energy Harvesting in Civil Engineering

To make the active and semi-active vibration control system in civil engineering get rid of external power supply, several kinds of structural vibration control systems based on energy harvesting and utilizing were summarized. On the basis of it, one vibration control system combing the magnetorheological （MR） damper with energy regeneration was presented, which could realize the self-powered and self-sensing control. The potential application, problem demanding prompt solution as well as the further research direction of this system were pointed out at last. The study results show that the system can be regarded as passive control device or semi-active control system with different control circuits, meanwhile, it can be used to develop the hybrid control system with other structural control system.
