Abstract | This paper presents a simplified HF injection method for permanent magnet synchronous motor (PMSM) sensorless control. The discussed HF injection scheme utilizes motor magnetic saliency property which contains the information of the rotor position due to magnet saturation. A high frequency voltage signal is injected into the d-axis winding in order to detect the magnetic saliency and estimate the rotor position. Then filters are used to analyze motor d-axis current and to extract rotor position information. In the proposed method, a band pass filter used in signal processing loop is omitted in order to avoid its phase shift and magnitude decrease. Thus fewer filters are used than those conventional HF injection schemes. The simulation and experimental results are presented based on the analysis of the proposed control strategy. |

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.
