%X Attitude Control System (ACS) for flexible space satellites demands great reliability, autonomy and robustness. These flexible structures face low stiffness due to minimal mass weight requirements. Satellite ACS design methods usually are based on a linear models without considering the differences sources of uncertainties, which can take to instability and/or inefficient performance. In this paper one investigates the robustness and performance of two different multivariable methodologies in designing the ACS for a rigid-flexible satellite. The first one is the traditional time domain approach called LQG (Lineal Quadratic Gaussian) and the second one is the frequency domain HInfinity approach. Although these control techniques have their particular characteristics, this investigation tray to highlighted the advantages and benefits of each technique as for the control algorithm implementation. During the satellite ACS design one observes the influence of increasing the numbers of flexible modes in the control system performance. The controller order is also relevant aspect in judging the control algorithm implementation into satellite onboard computer. A preliminary knowledge of robustness and performance of the control technique can represent more economical design process.
