| Abstract | This paper presents an approach to predictive and prognostic control, combining prognostics with predictive control to extend life, for the purpose of increasing the confidence levels for power converters used in aerospace applications. One goal of this work is to accelerate the adoption of new technologies, such as advanced power semiconductor devices. While the devices are immature the technology provides significant overall performance advantages. Using prognostication it is hoped to significantly increase the confidence levels for successful mission completion and so overcome reservations about adopting these new technologies. The methodology uses predictive modeling and simple, robust, sensing, attempting to avoid excessive sensing requirements in the prognostics of complex converters. This approach requires detailed knowledge of the dominant aging and failure mechanisms, the physical driving forces behind these mechanisms and the observable precursors of failure. The precise history of the power converter system, combined with measurement and modeling, can then predict whether the system can operate successfully for a given duration, with a high degree of confidence. The information could also be used to guide decisions about the future use or loading of specific converters in larger, parallel, redundant systems. |

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.
