| Abstract | The paper proposes a sensorless control strategy for long primary segmented permanent magnet linear synchronous motor(LPSPMLSM) used in electromagnetic catapult .Aiming at characteristics of parameter changes of LPSPMLSM, researchers mean to establish mathematical models of the motor. In accordance with the analysis of mathematical models of the motor, this paper presents an ameliorated sliding mode observer to acquire smooth observed back electromotive force (EMF). Besides, the method of two segments' observation of back EMF and Synchronization solves the both speed and position observation problem when movers move in single stator or transgress two stators. In that way, speed closed-loop control which has high dynamic response ability can be achievable by the sensorless algorithm. Ultimately, through the verification of Simulation testing, segmented motor can satisfy the demand of EML field by using control algorithm mentioned above. |

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.
