| Abstract | A new method for rotor sensorless speed estimation of line-connected induction machines is proposed in this paper. Considering that it is difficult to install speed sensor for submersible induction motor in some specific situations such as special high temperature working environment, the proposed technique of recurrent multilayer neural network is used to estimate the speed of sensorless submersible induction motor. The stator current measured by data collector is analyzed by wavelet, thus the influence of high frequency noisy caused by high temperature is filtered off. Since the useful signal is extracted as sample input, and the speed signal collected by speed sensor as sample output, a neural network is trained on the principle of "training off-line, estimating on-line ", so that the network can estimate the speed only using stator current. Experimental results prove that the proposed method has very high precision and good dynamic quality. Furthermore, the estimation results can provide powerful security for closed-loop control and fault diagnosis. |

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.
