| Abstract | Rotor angle calculation using flux estimation is a straightforward approach to sensorless control of synchronous reluctance motor (SYRM), but the dc offset can cause an increasing error in pure integrator used in this estimator. In this paper to control motor at low speed region a modified programmable cascaded low pass filters (MPCPLF) is proposed. MPCLPF is suggested because programmable cascade low pass filters (PCLPF), which has previously been applied to induction motors, has some problems in low speed area. In addition PCLPF is affected by the parameter fluctuation. To overcome the problem an online parameter identification method based on block pulse function also is proposed. In this method the parameter identification is not affected by position estimation accuracy. The experimental system includes a PC-based control with real time Linux as operating system. And to acquire data form sensors and to send commands to the system an ALTERA complex programmable logic device (CPLD) is used. The experimental results show the proposed method performs well and speed estimation, angles estimation and parameter identification are correct. Also it is shown sensorless vector control is achieved at low speed as well as high speed using proposed method |

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.
