This paper presents an adaptive detumbling method for non-rigid satellites with unknown dynamics. The challenge lies in stabilizing satellites with uncertain flexible dynamics, particularly when they are tumbling. The proposed method models the satellite as a two-link serial chain with unknown stiffness and damping, unlike previous rigid-body approaches. Two space tugs are used as servicers to detumble the satellite, despite uncertainties in the satellite's mass, inertia, stiffness, and contact points. The method addresses the need for robust control of both rotational and translational motion, which is critical for satellite stabilization. The paper introduces a decentralized adaptive controller that uses a Lyapunov-like function to ensure system stability. Simulation results demonstrate the effectiveness of the method, showing that the satellite's angular and linear velocities converge to zero, and the system remains stable. The controller adapts to unknown parameters, making it suitable for complex satellite detumbling tasks. The approach provides a robust solution for handling the uncertainties associated with non-rigid satellite dynamics.This paper presents an adaptive detumbling method for non-rigid satellites with unknown dynamics.
