Attitude Control and Vibration Suppression of the 1st Mode of Spacecraft with Flexible Structures Using Input Shaping

Abstract

In recent years, vibration of flexible structures such as solar battery paddles is a problem in attitude control of satellites. Input Shaping (IS) is an effective technique to suppress such vibration, in which multiple input signals are created to cancel its own vibration. This paper analytically describes the influence of the IS-signals upon the attitude of spacecraft, which realizes the vibration control and attitude control of spacecraft at the same time. Numerical simulation is conducted to verify the efficiency of the proposed method.
