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

This article investigates the secure consensus control problem for multi-unmanned aerial vehicles (uncrewed aerial vehicles (UAVs)) attitude system under channel fading. By decomposing the attitude system, an attitude privacy protection scheme is proposed, enhancing communication security through the transmission of only partial attitude angles. Under UAV channel fading, a distributed observer incorporating a detection factor and compensation mechanism is proposed to ensure both transmission accuracy and observation precision. Furthermore, to enhance tracking performance, a secure prescribed performance control (PPC) strategy based on preset trajectory is proposed. This strategy achieves the PPC without relying on complete information of UAVs. Ultimately, a simulation example involving UAVs demonstrates the feasibility and effectiveness of the proposed control scheme.
