Global adaptive disturbance rejection for nonlinear multi-stationed control systems

This paper studies a global distributed disturbance rejection problem for a class of multi-stationed and interconnected systems by a networked feedback controller. By incorporating an adaptive control technique, we present a networked internal model approach to solving a global output regulation problem. The study is motivated by and in turn applies to a control problem of accommodating external disturbance torques in a large space telescope (LST) system. Regarding this LST system, it is shown that a global distributed regulator can be constructed leading to the asymptotic stabilization while completely accommodate its disturbance torques.
