| Abstract | Speed identification is important to apply the permanent magnet synchronous motor system on the situation that need speed signal but without speed sensor. Taking system dynamic mathematics model as the investigated subject, set up the speed identification adaptive system of the enhanced magnetism motor system on the basic of Model Reference Adaptive System and POPOV's hyperstability theory. Derive the equivalence nonlinear feedback system of the speed identification adaptive system. Prove its stability and dynamic follow character. There is no pure integration, moment of inertia and system load in the speed estimation system. Taking system mechanic model as the verified subject, studied the speed estimation algorithms performance when the system works in drive, regenerative braking operation mode and disturbance happens to the motor system. Bench test verified the speed estimator when the system in acceleration. The results show that the identification speed can follow the real speed quickly in above all operation modes and the estimation error is small. The results of dynamic performance study are the basic of optimization of its control performance. |

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.
