| Abstract | An initial rotor position estimation method which is independent of the magnetic saliency is proposed for the main generator (MG) of aircraft three-stage wound-rotor synchronous starter/generators. Voltage signals are injected into the stator of the MG and the field current response of the MG is evaluated in this method. Owing to the brushless excitation structure, the field current of the MG cannot be measured directly. Thus, estimation of the field current of the MG is performed first. Then, high-frequency sinusoidal and pulse voltages are injected into the stator windings of the MG separately and the induced field current of the MG, estimated from the main exciter side, is regarded as the indicator for the initial rotor position of the MG. Simulation tests are carried out to verify the method and the results are presented and analysed. |

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.
