Abstract | This paper proposes an improved model predictive control (MPC) algorithm for the direct torque and flux control of induction motors (IMs) using the three- level inverter. To reduce the calculation amount, which is the drawback of MPC, first the reference value and the state of the motor are analyzed to preselect the calculation region for the cost function; by only subdividing the voltage vectors in the selected region, the reference voltage vector is selected by the MPC algorithm. The selected voltage vector applies the output voltage to the actual system through the space vector modulation (SVM) method. Even though the proposed MPC algorithm has a slight increase of calculation compared to the conventional MPC, it can control the induction motor more precisely. The effectiveness of the proposed MPC method is verified through simulation. The simulation result proves that new strategies provides low torque ripple performance. |

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.
