Distributed Network Control for Spacecraft Attitude Regulation on the Special Orthogonal Group

A distributed network attitude control scheme is proposed on the special orthogonal group of rotation SO(3) for a spacecraft integrated with multiple cellular space modules. Lever aging the passivity theory, a set of parallel sub-controllers, corresponding to actuators embedded within the cellular space modules, is developed based on a gain-scheduled control framework, and interconnected through a designed communication topology tailored for distributed control implementation. The closed-loop stability is guaranteed by the proposed passivity-based networked gain scheduled control scheme. Numerical simulations are conducted to validate the effectiveness of the proposed scheme, demonstrating its ability to reduce initial actuator loads and maintain robustness in the presence of actuation failures.
