Research into a Consistency Cooperative Control Method for Attitude Orbit Coupling of SAR Satellite Formations under Communication Constraints

To solve the problem of communication delays and topology changes achieve a high-precision formation configuration control index in flight SAR (synthetic aperture radar) satellite formations, this paper studies consistency cooperative attitude orbit coupling for formations under constraints. First, establishes relative motion state error equation formations. Considering capacity constraints actuators, designs hierarchical saturated controller coupling. Second, uses Lyapunov direct method to prove stability designed consistent uncertain space disturbances. Finally, simulates verifies controller. The results show that saturation can meet requirements maintenance accuracy Earth target observation missions.
