Abstract | The high-performance motor drive system requires fast dynamic response, as well as good anti-disturbance capabilities. Permanent magnet synchronous motor (PMSM) is a strongly coupled nonlinear system, which has time-varying variables. For high-precision tracking control, the time of the current response is relatively close to the time of the speed response, which poses a major challenge of using vector control based on field orientation. Therefore nonlinear control approaches are good alternatives. In this paper, we propose a direct feedback linearization control method with nonlinear disturbance observer to achieve high control performance. The nonlinear disturbance observer is designed to estimate various disturbances, such as parameter variations, modeling errors and external disturbances. The estimated value is then used to construct a feed-forward compensator added to the control input. The simulation results demonstrate the effectiveness of this control method. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
