This paper is concerned with large angle slew maneuvering of flexible spacecraft

consisting of a rigid central body and a flexible beam. The dynamic model is derived by the assumption mode method. The variable structure control(VSC) method is applied to drive slew maneuvering using jet and fly wheel as actuators. To suppress the simultaneous elastic vibration in movement

an elastic stabilizer is designed by using the LQR control method. Numerical simulation results are presented to show the effectiveness of the proposed control strategy.
