Abstract | In this paper, a kind of nonlinear dynamic model of dual-arm free-floating space robot systems is presented based on Lagrange method. Based on the result, the control problem for space manipulator to track the desired trajectory in joint workspace is discussed. Because of the high structure complexity and the parameter uncertainty of space manipulator systems, the scheme of variable structure sliding-mode control with better robustness to uncertainty and disturbance is proposed. Fuzzy controllers are designed at the aim of chattering reduction and rapid response. The fuzzy controllers can tune the sliding control law automatically according to the relationship between system state and switching manifold. The effect of the controller is testified by computer simulation. |

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.
