| Abstract | Atomic force microscopy (AFM) is an advanced technique which aims to scan a sample through the use of a probe or a tip; however, conventional atomic force microscope system suffers from the limitation of small scanning range, due to the short travelling range of piezoelectric actuation. In this paper, we propose a large measurement- range AFM scanning system which combines both fine positioners of piezoelectric and electromagnetic actuations. While the piezoelectric positioner provides high speed scanning with nanometer resolution, the precision electromagnetic positioner is capable of 1 $mm^{2}$ large field positioning with 30 nm rms error. The overall design of the stage consists of 4 pairs of electromagnetic actuator, monolithic serial flexure guidance with compression springs, an eddy current damper, and a commercial xyz piezoelectric positioner. Besides, a stationary compact disk/digital versatile disk pick-up-head (CD/DVD PUH) is used to measure the amplitude of samples. Moreover, an adaptive sliding mode controller based on the analytical modeling is used to overcome the unmodeled system uncertainties and external disturbances. Finally, preliminary experiments are presented, demonstrating feasibility of the proposed system. |

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.
