Satellite Formation-Containment Control Emphasis on Collision Avoidance and Uncertainty Suppression

Area of Science:

• Aerospace Engineering
• Control Systems Theory
• Robotics

Background:

• Satellite formations require precise control for mission success.
• Ensuring safety through collision avoidance and managing external uncertainties are critical challenges.

Purpose of the Study:

• To develop an adaptive robust control scheme for satellite formation-containment flying.
• To address both collision avoidance and uncertainty suppression for safe and reliable operations.

Main Methods:

• An adaptive law estimates time-varying uncertainty bounds online.
• Formation-containment control is reformulated as a constraint-following problem.
• An η-measure quantifies constraint-following error for control design.

Main Results:

• The proposed adaptive robust control ensures uniformly bounded errors.
• The control scheme effectively handles time-varying uncertainties.
• Satellites approximately follow collision avoidance, formation, and containment constraints.

Conclusions:

• The adaptive robust control scheme achieves satellite formation-containment with enhanced safety.
• The approach successfully suppresses uncertainties and ensures collision avoidance.
• This method provides a robust solution for complex satellite formation missions.
