- 🚀 Nonlinear relative orbital dynamics (with gravity gradient)
- ⚙️ Lyapunov control law:
u = -Kr·δr - Δa - P·δv - 📉 Control saturation (e.g. 1 mm/s²)
- 🌍 Animated 3D orbits with
plot_Earth - 📊 Time-history plots: position, velocity, control input
- 🧮 Computes control effort: ∫‖u‖ dt
- 🌑 Dark-themed visualizations
