Abstract | This paper proposes a new principle of sensorless position estimation for a switched reluctance motor (SRM) drive, based on an improved flux/current method. The estimation algorithm makes full use of the structural symmetry of SRM, and only some specific position flux linkage data are needed, which greatly decrease the need for the high speed and capacity of microcontroller. The proposed method does not require external hardware and hence the reliability of the scheme is expected to be good while not adding to the system cost. Preliminary investigation shows that the proposed sensorless scheme can give position information with high resolution for speeds. The basic principle of this method is analyzed, simulations and real-time implementation of the sensorless scheme using Matlab-simulink are carried out based on a 12/8 SRM, the result of which shows the feasibility of the algorithm. Hardware aspects along with the implementation details of the sensorless scheme are discussed briefly. Experimental investigation is underway and complete set of test results will be provided in the next step work. |

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.
