Based on the PS/T Method Control Design of Flexible Systems

Abstract:

The lightly damped resonant poles of flexible system increased norm of coprime factor perturbation, which reduced robust of system after loop shaping design. This paper proposes approaches considering the performance of constraints, to select performance weight function through disturbance attenuation and to adjust the complementary sensitivity weight function through design index. The flexible satellite's attitude control demonstrates that the two approaches are able to rapidly select weight function under ensuring the system's robust and have the ability to depress disturbance.
