| Abstract | The concept of cell-to-cell mapping is proposed for the track accessing controller design of computer disk file actuators. Conventional design approach uses the classical bang-bang control theory. The result does not include any structural resonance of the actuator, and the constraints are only imposed in an ad hoc fashion. No optimization results can be claimed. By working with the cell-to-cell mapping, the structural resonance can be included without any additional difficulty, and the constraints can also be included in the consideration while still satisfying the optimal control requirement. The results showed that when pure inertia model is assumed, classical bang-bang control configuration for the velocity profile is still obtained. When more complex model is used, the classical bang-bang control does not achieve optimization. A more delicate velocity profile is thus necessary. |

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.
