Abstract | For the problem of position and force trajectory tracking of flexible joint manipulators whose motion is constrained in the end, a finite-time position/force control strategy is proposed using adaptive terminal sliding mode. Firstly, position control and force control are decoupled according to the coordinate transformation and a reduced dynamic model for the manipulator is obtained. Then a new terminal sliding mode is established and an adaptive position/force control law is designed to overcome the uncertainties of the dynamic model. The system variables can be driven to reach the terminal sliding mode and slide to equilibrium point along the mode in finite time. Unlike previous position/force control strategies, this strategy can make both position and force tracking errors of the manipulator converge to zero in finite time. Simulation results are presented to validate the proposed method. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
