Abstract | For the trajectory tracking control problem of biped multi-linked robots with uncertain disturbances, a global finite-time tracking controller is proposed based on terminal sliding mode control method. First, according to the features of forward dynamic model of biped multi-linked robots, the sliding mode controller is designed based on the terminal sliding mode theory. Under the designed controller, the tracking error will not only reach the terminal sliding mode surface from any initial states but also converges to the origin along the sliding mode surface in finite time . Second, due to the non-continuity of the controller, the chattering phenomenon occurs. To this end, a modified saturation function is utilized to substitute the sign function in the designed controller, and thus the chattering can be eliminated. Finally, simulation results verify the effectiveness of this 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.
