Preset-Trajectory and State-Decomposition-Based Secure Consensus Control for UAVs With Channel Fading.

Area of Science:

• Robotics and Control Systems
• Networked Systems Security
• Aerospace Engineering

Background:

• Secure consensus control is crucial for multi-unmanned aerial vehicle (UAV) systems.
• Channel fading in communication links poses significant challenges to system stability and security.
• Existing methods often require full state information, limiting practical application.

Purpose of the Study:

• To develop a secure consensus control strategy for multi-UAV attitude systems under channel fading.
• To enhance communication security by protecting attitude information.
• To improve tracking performance and system robustness without complete UAV information.

Main Methods:

• Decomposition of the attitude system to enable partial angle transmission for privacy.
• Design of a distributed observer with detection and compensation for channel fading.
• Implementation of a secure prescribed performance control (PPC) strategy based on preset trajectories.

Main Results:

• The proposed attitude privacy protection scheme effectively enhances communication security.
• The distributed observer ensures accurate transmission and precise observation under fading conditions.
• The secure PPC strategy achieves desired tracking performance without full UAV state knowledge.

Conclusions:

• The developed secure consensus control scheme is feasible and effective for multi-UAV attitude systems.
• The integration of privacy protection and robust control addresses key challenges in networked UAV operations.
• This research contributes to the advancement of secure and reliable autonomous aerial systems.
