Vibration Control of Flexible Space Structures Based on Reduced Order Modeling Method and Filtered LQ Control Theory

Abstract

In this paper, we proposes a new control technique for reducing the vibration of a flexible space structure arranged in series, such as a pair of solar paddles of the space station. In this study, the reduced order model for controlling the first and the second bending modes of the structure is derived. For designing the controller, the filtered Linear Quadratic Optimum control theory (LQ control theory) is used. The reduced order model and the controller design are verified by simulations and experiments.
