| Abstract | This paper presents an optimal control method for consensus of spacecrafts cluster flight based on linear quadratic regulation (LQR). Firstly, we employ period-delayed errors as states of cooperative control and derive period-delayed errors dynamics of single spacecraft and the cluster of spacecrafts. Then, we converts the control problem of spacecrafts cluster flight periodically bounded relative motion into the consensus of period-delayed errors. We devise a feedback control law with a positive scalar called coupling gain. The notion of consensus region used in the consensus problem of multi-agent systems and the graph theory are analyzed. Considering the communication topology, we can select a suitable coupling gain according to the consensus region. Employing LQR-based optimal method, we can design the feedback control gain. So that the period-delayed errors of the spacecrafts cluster and semi-major axis of each spacecraft tend to consensus, which result in spacecrafts cluster emerging the global coordination swarming-like behavior. Numerical simulations are conducted verifying the effectiveness of the proposed LQR-based optimal control method for consensus of spacecrafts cluster flight. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
