| Abstract | The development of many advanced technology products depends entirely on its components which tolerances or dimensions need to meet the micro-or even nanotechnology range requirements. It is generally accepted that position servo controller of machine tool is the main concern in achieving the high machining precision. Nanometric-level positioning accuracy of the ultra precision machine tool is difficult to obtain, particularly with parameters uncertainties, external nonlinear disturbances. In order to compensate above disadvantages, a model reference adaptive control method was proposed to adjust the important and main position loop of the three closed-loop control system which was designed mainly for regulating mechanical transmission modules and counterbalancing internal and external disturbances. In addition, the other two close loops were built in adjusting the acceleration and velocity of the electric drive system respectively that aimed to achieve the fast and precise response and increase dynamic stiffness. The results illustrated satisfactory performances in steady state error, load capability, high rapidity and so on. |

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.
