Analysis and Design of Synchronization for Heterogeneous Network

Area of Science:

• Control Systems Engineering
• Networked Systems
• Applied Mathematics

Background:

• Heterogeneous networks require robust synchronization mechanisms.
• Event-triggering communication offers efficiency but poses challenges for stability.
• Intermittent communication can lead to data loss and synchronization errors.

Purpose of the Study:

• To develop an event-triggering communication strategy for synchronizing heterogeneous networks.
• To design controllers that ensure exponential tracking and synchronization.
• To establish a positive lower bound for inter-event intervals.

Main Methods:

• Designing a controller with a reference generator (RG) and regulator for each node.
• Utilizing predicted relative information to minimize transmitted data.
• Implementing an event-triggering strategy with a time-dependent threshold.
• Analyzing the stability and synchronization performance.

Main Results:

• Achieved exponential tracking of the target trajectory by all RGs.
• Ensured synchronization of each node with its RG via the regulator.
• Guaranteed a positive lower bound for inter-event intervals, ensuring system stability.
• Demonstrated the effectiveness of the proposed strategy through a numerical example.

Conclusions:

• The proposed event-triggering strategy effectively synchronizes heterogeneous networks.
• The method significantly reduces communication load while maintaining performance.
• The findings contribute to efficient and stable networked control systems.
