Modeling and Robust Control of a Flexible Solar Array Paddle

Abstract

In this paper, modeling and vibration control of a flexible solar array paddle are considered. We first derive a partial differential equation and a set of boundary conditions of the flexible solar array paddle and ordinary differential equations of angles of rotation of motors. On the basis of a finite-dimensional modal model, an optimal controller with low-pass property and a robust H_∞ controller for the flexible solar array paddle are constructed. Simulations and experiments have been carried out.
