Abstract

This paper presents a commonly used magnetic momentum controller for satellites augmented with an L1 adaptive controller. In particular, the main objective of the study is to investigate the ability of L1 adaptive control to improve the momentum de-saturation performance and add more robustness to the existing control architecture in the presence of uncertainties in the geomagnetic field model available on-board and used in the controller design. Existing non-adaptive controllers use Earth's magnetic field measurements or fairly accurate models. The results presented in this paper suggest that L1 adaptive control is able to provide robust magnetic momentum control with a rough geomagnetic field model in the presence of model uncertainties and disturbances.
