Abstract | In the beginning, the kinematic model, dynamic model of a differential mobile robot (DMR), and the dynamic model of left- and right-wheel DC motors are combined to be a controlled system. The control inputs of the proposed controlled system include the input voltages for the left- and right-wheel motors, i.e., two inputs. On the other hand, the system outputs contain two-dimension position and its orientation, i.e., three outputs. Due to the under-actuated characteristic, the sliding surface using directly controlled output is designed so that the number of control input and sliding surface is the same, and that the indirectly controlled output is also controlled. Under uncertain environment including friction and uncertainty, the sliding-mode under-actuated control (SMUC) with suitable conditions is designed such that an asymptotical tracking result is obtained. To enhance system performance, an on-line fuzzy modeling of friction and uncertainty is employed to design a fuzzy model-based sliding-mode under-actuated control (FSMUC). Finally, the proposed hybrid fuzzy sliding-mode under-actuated control (HFSMUC) combining SMUC and FSMUC with a transition maintains both advantages of SMUC and FSMUC and simultaneously avoids the disadvantages coming from SMCU and FSUMC. |

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.
