Designing a Robust Nonlinear Dynamic Inversion Controller for Spacecraft Formation Flying

Figure 9

Simulation results of the position tracking error of the spacecrafts controlled by NDI and RNDI. The black thin line represents the trajectories of the spacecraft controlled by NDI while the blue thick line represents the trajectories of the spacecraft controlled by RNDI.
