| Abstract | This work describes how a Neuro-Fuzzy network (ANFIS, Adaptive Network-based Fuzzy Inrerence System) is used to control an Induction Motor Drive-based Direct Torque Control strateLv to improve the dynamic behavior or the system and simplify the conventional direct torque control scheme. The Neuro-Fuzzy controller¿s structure guides the torque and stator flux error signals through the fuzzy inference to get an output that takes the form of a space voltage vector to be modulated by the inverter. Besides this intelligent controller, Space Vector Modulation is applied to avoid hysteresis bands and switching tables which are common in the conventional scheme. Under this frame it is possible to set a constant value for the switching frequency and, in general, improve the dynamic behavior of the system. Simulations are presented to show that the proposed Intelligent System is characterized not only by simple mathematical models, but also by very fast torque and flux responses. Furthermore, zero-steady-state error in torque and flux is gotten thanks to inverse learning and the tuning algorithm appiied to the network. This control also provides a natural and well-defined human-machine interaction. |

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.
