Multi-Spacecraft Formation Attitude Coordinated Control with Communication Delay

This project tackles the hard problem of keeping the attitudes (orientations) of a group of spacecraft aligned when there are constant communication delays. In a distributed satellite network, any delay in sharing information can quickly hurt performance and even break the formation’s stability. To fight these problems, we study a coordinated attitude‑control algorithm that uses double‑exponential control theory. The idea is to speed up the convergence of auxiliary variables that are built from the tracking errors of the system. This makes the formation much more robust to network latency. We prove the system’s stability with a Lyapunov‑Krasovskii functional. The analysis gives clear conditions that guarantee the attitude‑synchronization errors will go

to zero over time, even with communication delays. We test the method with numerical simulations of a multi‑spacecraft formation. The results show that the double‑exponential auxiliary‑variable approach keeps the spacecraft attitudes tightly synchronized. The material also includes MATLAB/Simulink support for: – modeling time‑delayed multi‑agent systems, – setting up the control laws, – performing the stability analysis. This provides a practical framework for advanced research in guidance, navigation, and control.
