| 英文摘要 |
| The distributed leaderless consensus problem for relative orbit of modular spacecrafts is studied based on the
consensus theory of multi-agent systems. The interaction topology among the modules is a general directed graph. When
all modules are with unknown masses, we propose an adaptive control algorithm based on the information of individual
module and its neighbors, without the need of relative velocity measurements. To compensate with the bounded external
disturbances, we introduce a variable structure control term with an adaptive updating law. The closed-loop system is
proved to be asymptotically stable. Moreover, the proposed control algorithm is totally distributed; its complexity will not
increase when the number of modules becomes greater. Simulation results of a scenario of six modules are conducted to
validate the effectiveness of the proposed control schemes. |
