| contents | This paper presents prototype testing and a control allocation algorithm for the Cable-Actuated Bio-inspired Lightweight Elastic Solar Sail (CABLESSail) concept aimed at performing momentum management of a solar sail. CABLESSail uses actuated cables routed along the structural booms of the solar sail to control the shape of the solar sail and changes the solar radiation pressure disturbance torques acting on it. Small-scale prototype tests of CABLESSail are presented in this paper, which demonstrate the effectiveness of cable actuation on deployable booms. A novel control allocation method is also presented in this paper that provides a computationally-efficient manner to determine the deformations required in each of the structural booms to impart the desired momentum management torque on the solar sail. Numerical simulation results with the proposed algorithm demonstrate robustness to uncertainty in the shape of the sail membrane, resulting in reliable generation of momentum management torques that exceed or meet the capabilities of state-of-the-art solar sail actuators. Both the prototype tests and control allocation methods presented in this paper represent key steps in raising the technology readiness level of the CABLESSail concept. |
