| Abstract | This paper describes the application of ANNs observer based on the extended Kalman filter (EKF) for rotor resistance, Mutual inductance and rotor speed estimation of an induction motor, in order to overcome the constraint of adjustment of the covariance matrices and to improve the estimate of these last three parameters. It is an observer for non-linear systems; it is applied to the indirect field oriented control. The magnetic saturation, the operating temperature and difficulties in using sensors for speed measurement are one of the sources of parameters variations. The indirect field oriented control (IFOC) is highly sensitive to these variations and to the noise. To fix this problem, the artificial neural networks (ANNs) observer based on the extended Kalman filter (EKF) is applied to sensorless parameters estimation of an induction motor. The general structure of the EKF is reviewed and the various systems vectors and matrices are defined. The elements of the covariance matrices are properly selected. The EKF associated to the neural network (EKF-ANNs) trained off line algorithm are used to estimate the rotor resistance, the mutual inductance and the rotor speed. By including these parameters as states variables, the EKF equations are established from a discrete two-axis model of the three-phase induction motor. The results obtained with the proposed observer are more efficient than the results obtained with classical EKF. |

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.
