| Abstract | A novel precise position tracking controller is presented for permanent magnet synchronous motors (PMSMs). The proposed controller consisting of non-linear extended state observer (ESO), tracking differentiator (TD) and dynamic surface control (DSC) can reject disturbance and can prevent PMSMs from chaos with parameters falling into some special areas. Compared with the conventional DSC approach, the TD of the proposed controller is designed to remove the explosion problem. Further, non-linear ESO is designed to estimate the unmeasurable states and uncertainties of system, which together with TD significantly ameliorate the tracking performance and improve the disturbance rejection ability of system output in the presence of uncertainties and unmodelled dynamics of PMSMs. Different from the available control methods of PMSMs in reference, both the transient and steady-state stability of the closed-loop control system is proved by the Lyapunov method. Finally, comparative simulations are completed to demonstrate that the precise trajectory tracking performance, chaos-suppressing performance and disturbance rejection performance of the proposed controller can be guaranteed. |

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.
