| Abstract | A new approach is proposed in the present paper to perform an indirect speed estimation on sensorless field oriented induction motor drives. It is based on the injection of a suitable high frequency current test signal, that causes a small oscillation of the rotor flux angular frequency and the generation of a zero sequence stator voltage component. The motor speed can be expressed as a function of only the ripple generated on the rotor flux angular frequency and stator current components. Therefore, the amplitude of the ripple on the rotor flux angular frequency is directly measured from the frequency of the zero sequence voltage component and used to indirectly estimate the rotor speed in any operating conditions, including no load and zero stator frequency. Speed estimation according to the proposed approach is fully insensitive to motor parameter variations, features a large bandwidth and can be used on either IFOC, DFOC and DTC sensorless schemes. |

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.
