Nonovershooting Space Tether Deployment with Explicit Constraint of Positive Deployment Velocity

摘要

In this paper, we propose a control law for the passive tether deployment. First, a reference trajectory of nonovershoot tether length, non-negative deployment velocity and tether tension is designed with the consideration of the stability of internal dynamics of TSS. Second, a tension control law with pulse-width pulse-frequency modulation is developed to track the reference trajectory. The effectiveness of the proposed control law is demonstrated by simulations.
