Abstract | A current control strategy for an asynchronous machine was formulated, studied, and simulated. In the design of the controller a time-varying multiple-input multiple-output model is used to describe the relationship between stator current and the voltage. However, in the discrete equivalent MIMO model the dominant parameters have a restricted variation range due to the discretization. On the other hand, since this model depends only on the terminal quantities, its parameters can be easily estimated. The current control was implemented using the predictive technique. The parameters of the controller were obtained using the recursive least squares estimation technique. The performance of the system was evaluated using the transfer matrix approach. The plotting of the Bode curves and the computation of the zeros and poles of the model were used to predict the closed-loop static and dynamic behavior. The time response results agreed with those predicted using the frequency response technique. |

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.
