NOVEL SPACE SCIENCE TEST VIA ADAPTIVE CONTROL AND INTEGRAL CONCURRENT LEARNING LEVERAGING ON-ORBIT CUBESAT STRUCTURAL IDENTIFICATION

Abstract

The foundations for attitude-orbit maneuvering-excitation and simultaneous mode estimation of highly flexible spacecraft, enabling on orbit autonomous testing of the entire structure, thus saving cost and time on the ground, and capturing unknown deviations from computer models that may be caused by poor modeling, storage, and launch stresses. Rigorous Lyapunov proofs can be provided using the proposed techniques, guaranteeing stability of the controlled system and convergence of the unknown parameters to their true values. Project will focus on controlling the spacecraft attitude and the behavior of key locations of the most flexible components (i.e., the extremities), setting the natural frequencies as the uncertain parameters to estimate.
