This paper studies a decentralized control for a class of space structures which is constructed on orbit. For general mechanical systems with collocated sensors and actuators, it is known effective to use a symmetric controller. The symmetric controller guarantees robust stability of the closed loop system by virtue of its structure having positive definite or positive semi definite symmetric coefficient matrices. We proposes an optimal design method of the symmetric decentralized controller in the sense of H_∞ norm before and after construction. In the synthesis, the optimal controller is obtained by solving linear matrix inequalities reduced from the bounded real lemma. Then we evaluate its performance by a numerical simulation for a simple LSS model.
