Abstract :
This paper considers robust decentralized control of large space structures composed of interconnected subsystems(substructures) by flexible links. A local controller is applied to each subsystem with collocated displacement/angle sensors and force/torque actuators. An N-th order proper controller using only displacement/angle feedback, is introduced at each input channel to control position and attitude of the space structures. It is shown that both the closed-loop subsystems and the overall closed-loop system become robustly stable under the condition in which the controller parameters are chosen to lead phase at appropriate frequencies in each subsystem.
