Due to the space missions' limited budget, microsatellite would be an economical choice, so there has been a great decrease in size and weight. Micro satellite is vulnerable to space environmental disturbances and perturbation of controller. As to the multiplicative perturbation in attitude controller, this paper investigates a robust H∞ controller design with model uncertainties and subject to external...
In this paper, the relative navigation algorithm of chaser spacecraft with orbit maneuvering is investigated. Based on the relative motion dynamic model and linear relative measurement model, a robust H∞ filter for chaser spacecraft is proposed, which contains affine norm-bounded uncertainties, disturbances, and non-Gaussian noise. The necessary and sufficient conditions for the existence of robust...
