Abstract | Magnetic Levitation Systems are used to levitate a ferromagnetic object in the air. It has a wide area of applications because it eradicates energy losses that occur due to friction of the surface. In this paper, nonlinear controllers have been designed by using backstepping, integral backstepping and synergetic control techniques to obtain certain control objectives. Nonlinear controllers have been designed because of nonlinear dynamics present in the system model. It is required to generate a certain amount of flux by applying control input to the system. The magnetic flux is then used to levitate the body in air at a certain distance from the coil so that the movement of the body within that magnetic flux is negligible. The magnetic force provides an acceleration against the earth gravitational force to lift the body towards the coil. For each nonlinear controller, Lyapunov based theory has been used to check the global asymptotic stability of the system. MATLAB/Simulink environment is then used to analyze the system's performance for the proposed controllers. Moreover, a comparative analysis of proposed controllers has been given with linear (PI) controller. |

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.
