    Abstract:
    Objective In order to tackle the challenges of low reliability, weak risk resistance and limited real-time performance in existing centralized control architectures for active vibration isolation systems, and considering the current state of research on vibration systems and edge computing, this study proposes a distributed control architecture for large-scale shipborne active vibration isolation systems based on edge computing.
    Methods First, the traits of the centralized and distributed control approaches are analyzed. Second, the entire architecture of the control system is studied, leading to the design of its hierarchical structure and overall layout, which is partitioned into three levels: cloud, edge and end. The architectural design and interconnections of each level are expounded upon in detail. Finally, an experimental platform is created, and the system's reliability and real-time performance are evaluated through testing.
    Results The experimental results indicate that the designed system architecture continues to operate normally under sudden circumstances, demonstrating stability and reliability. Moreover, the clock synchronization deviation is reduced to 1 microsecond, enhancing the system's real-time performance.
    Conclusion The system architecture is rationally and efficiently designed, effectively enhancing the reliability, risk resistance and real-time performance of the vibration isolation system
