Dynamics-based mass property identification of non-cooperative space target

Abstract

A novel dynamics-based identification methodology is presented in this paper. This approach is able to identify the total mass property of space robot after capturing non-cooperative target, and recursive least square algorithm is applied to implement that identification. Based on the modeling method of multi-body dynamics and geometric relationship, the mass property parameters of the jointing non-cooperative target and the end effector are obtained. Simulation results are also presented to verify the effectiveness of the proposed identification algorithm.
