摘要
针对分布式卫星编队飞行队形保持控制问题提出一种分布式协同控制算法,并给出该协同控制算法与编队卫星星间信息传递拓扑结构之间的关系。该协同控制算法以模型预测控制为基础,利用分布式编队卫星的自然特性以及编队卫星之间的信息传递拓扑结构,采用分布式的算法结构,设计分布式的模型预测协同控制算法。该控制算法是一种在线滚动优化控制算法,同时能够较好地解决存在状态约束、控制输入约束等情形下的各种控制问题。最后通过数值仿真验证了结果的有效性。仿真结果表明,当编队卫星星间信息传递拓扑结构中存在生成树时,提出的分布式协同控制算法能够有效地应用到编队卫星队形保持控制问题上来。
A distributed cooperative control algorithm is proposed in this paper for a class of distributed satellite formation keeping problem,and the relationship between the proposed algorithm and the topology structure of the information communication among foramtion flying satellites is presented.The proposed algorithm is based on model predictive control,and the nature and the topology structure of the distributed satellite formation,are used to design a distributed model predictive control algorithm in a distributed structure.The proposed algorithm is optimized over a finite time on line and can deal with the constrained contol problem well.Numerical simulations have demonstrated the effectiveness of the approach proposed.Simulation results show that the proposed algorithm can be applied to the distributed satellite formation keeping control problem effectively.
