This paper describes the attitude control problem of a flexible parameter varying spacecraft. Considered herein is the spacecraft consists of the main rigid body and some flexible solar panels which rotate at the orbital rate in order to generate more electricity. In this case, the interference characteristics of the elastic vibration of the panels and the attitude motion of the body changes depending on the panel angle. Therefore, the attitude control system of such spacecraft becomes parameter varying. This paper is intended to establish the systematic robust controller synthesis procedure for this problem by applying Gain Scheduling framework. This controller is designed by H_∞ sysnthesis via LMI. Capability of the method is investigated by the numerical study using the model of the ETS-VI spacecraft.
