TL;DR: Robust adaptive pose tracking control for multiple spacecraft rendezvous with collision avoidance considers model uncertainties, disturbances, path constraints, and collision avoidance. A 6DOF robust adaptive controller is designed to track the target spacecraft and avoid collisions.

Abstract: This paper investigates the problem of position tracking and attitude synchronization for multiple chaser spacecraft rendezvous and docking with the target spacecraft, in which model uncertainties, unknown external disturbances, path constraints, and collision avoidance are considered. The coupled six-degrees-of-freedom (6DOF) dynamic model is adopted for spacecraft relative motion. By integrating the artificial potential function (APF), a 6DOF robust adaptive controller is designed. In addition, unknown parameters are estimated with a norm-estimation-based adaptive method. The stability of the system is proved by Lyapunov theory and a simulation example is given to verify the theoretical results.

Swarm aggregations using artificial potentials and sliding-mode control
TL;DR: This paper considers a control strategy of multiagent systems, or simply, swarms, based on artificial potential functions and the sliding-mode control technique, and considers a general model for vehicle dynamics of each agent (swarm member), and uses sliding- mode control theory to force their motion to obey the dynamics of the kinematic model.

Tracking control of spacecraft formation flying with collision avoidance
TL;DR: In this paper, a nonlinear adaptive feedback control law is developed by employing special potential functions and a kind of time-varying sliding manifold, to enable the spacecraft formation in a specific configuration by taking into account the obstacle avoidance requirement while tracking a moving target in a way of cooperation or not.

Adaptive Pose Control for Spacecraft Proximity Operations With Prescribed Performance Under Spatial Motion Constraints
TL;DR: The salient feature of the proposed method is that, by judiciously imposing the performance specifications on the pose tracking errors, it can enable the pursuer to accomplish the proximity operations in a designer-appointed time and ensure compliance with spatial motion constraints and avoid singularity of the attitude extraction algorithm.
