摘要

Nowadays an increasing number of space missions are using satellites with a rigid hub and long flexible solar panels and robotic arms. The increasing need for better pointing accuracy of such satellites can be achieved with more efficient controllers. One way to improve controller performance is estimating flexible parameters as elastic displacement continuously in the space environment. This paper presents the elastic displacement identification using the Kalman Filter. This technique is tested under several conditions considering cold start with coarse initial knowledge and varied measurement noise levels. Simulations results have showed the robustness and feasibility of the proposed procedure.
