| Abstract | In this paper, a Multi-mode switching guidance control strategy is proposed for the final translation phase space autonomous rendezvous and docking precision-guided control problem. Firstly, dynamic model for spacecraft rendezvous is established and analyzed under the target coordinates. Secondly, the final translation phase is divided into two parts, constant speed translation phase and inconstant speed translation phase. In the constant speed phase, PID controller is used for ensuring control precision. Considering the uncertainty and nonlinear characteristics of the system, a fuzzy controller is designed to realize the precise guidance for inconstant speed translation phase. The whole control process is based on the error threshold control method to reduce fuel consumption. The simulation results demonstrate the effectiveness of the proposed guidance control strategy. Finally, the method of converting the continuous control law into the relay-type control law is discussed. The relay-type control law is easier to realize in engineering application. |

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.
