Due to their onboard sensing, communication, and computational capabilities, wireless smart sensors, which have become popular for structural health monitoring applications, are an attractive option for implementing structural control systems. However, wireless smart sensors pose unique challenges, such as communication latency and unreliable communication, which make common centralized control systems over wireless networks less feasible. Previous research has implemented wireless structural control using decentralized approaches on semi-active control systems; however, these implementations are less sensitive to the challenges related to wireless structural control, because semi-active control systems are inherently stable.

Low-latency data acquisition and actuation hardware tailored for control limits any inherent delay due to the sensing and control components. Real-time wireless data acquisition and control strategies are implemented within the existing software framework.
