| Abstract | This paper proposed a special framework for positioning control of electro-magnetic suspension actuator (EMSA) system in multiple degrees of freedom (DOFs). A conceptual design of the EMSA system consists of a carrier and three active coils, which are utilized to provide the propulsion and levitation forces. The purpose of this research mainly focuses on stabilizing the positioning problem of the 2-D system with the purely non-contact magnetic forces. In view of the fact that a passive magnetic levitation system is an inherently unstable plant, therefore, in this study, we not only make one's utmost to reform the configuration but also design a controller to achieve the stability. Due to the magnetic suspension systems are nonlinear and the existed modeling errors, we apply an adaptive sliding mode controller to eliminate the system's uncertainties and to guarantee the whole system's performance. Finally, from simulation results, the achievement of the required performance of regulation for guiding-axis and tracking for positioning-axis can be validated. |

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.
