摘要无线智能传感器是结构健康监测的一种流行选择，是传统系留系统结构控制的一种令人兴奋的替代方案。其机载通信、传感、驱动和处理能力提供了反馈控制的所有组件，以限制地震和风期间的结构响应。然而，无线智能传感器对结构控制提出了独特的挑战，包括通信延迟、延迟和数据丢失。无线结构控制中的先前研究已经使用分散控制方法来克服这些固有的限制。然而，这些实验研究集中在半主动控制系统，其中的稳定性得到保证。因此，半主动无线控制实现对智能传感器施加的延迟和采样率限制不太敏感。本文介绍了分散无线主动控制的实验研究。无线控制系统的所有元件都是...
AbstractWireless smart sensors, a popular option for structural health monitoring, are an exciting alternative to traditional tethered systems for structural control. Their onboard communication, sensing, actuation, and processing capabilities offer all the components for feedback control to limit structural response during earthquakes and wind. However, wireless smart sensors pose unique challenges for structural control including communication latency, delays, and data loss. Previous research in wireless structural control has used decentralized control approaches to overcome these inherent limitations. However, these experimental investigations have focused on semiactive control systems, in which stability is guaranteed. Thus, the semiactive wireless control implementations are less sensitive to delays and sampling rate limitations imposed by the smart sensors. This paper presents an experimental investigation of decentralized wireless active control. All the elements of the wireless control system are...
