This paper investigates the integrated attitude control algorithm and steering law for agile small satellites configured with control moment gyroscope (CMG). Firstly, considering the deterioration over time of the typical pyramid-shaped CMG cluster with 4 single-gimbal CMGs, build the CMG dynamic model. Then, based on the adaptive control theory to design the integrated attitude control algorithm...
Stability analysis of multiagent systems under linear cyclic pursuit control is studied in this paper. Firstly, the conditions on which multi-agent systems still remain stable under linear cyclic pursuit control are proposed. we show that all the agents converge to a equilibrium point if multi-agent systems are stable. Then, a special property is discussed when the multi-agent systems are unstable...
Based on dynamics of satellites formation flying itself, J2 invariant formation can be capable of keeping the formation autonomously without consuming the fuel resource. However, this characteristic can be destroyed by the atmosphere perturbation. In this paper, based on the condition of existence of the .12 invariant formation, the reason of destroy of J2 invariant formation by atmosphere perturbation...
