| Abstract | A new flux observer suitable for DTC application is presented in this paper, which is capable of ensuring flux linkage to be perpendicular to back electromotive force, so that the stator flux linkage can be estimated accurately over a wide speed range. Therefore the proposed observer could solve those problems associated with conventional observer such as DC drift, magnetic saturation and inaccurate estimation of stator flux linkage at very low speed operation. The feasibility and correctness were verified by the DTC controller in a 2 kW PMSM setup via a digital signal processor (DSP). Experiment results indicate that the proposed observer is capable of estimating accurately the stator flux linkage including its amplitude and phase angle when motor runs at a very low frequency of 0.7 Hz and at the rated frequency of 100 Hz. The high performance operation for PMSM DTC using proposed flux observer has been achieved with satisfaction in laboratory |

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.
