| Abstract | We suggest an unusual new switching-mode control strategy for magnetic levitation. We show that the apparently simplest control strategy, one that relies on a single decision plane, is not capable of levitation, but relying on two decision planes is sufficient for levitation. We demonstrate that the information, whether the suspended object is above an upper reference plane or below a slightly lower reference plane or in between, is sufficient for activating a switch that energizes an electromagnet in such a manner that it stably supports the suspended object. We have analyzed the dynamic features of the suggested system theoretically and have investigated them by experiment and comprehensive simulation. An interesting dynamics associated with chaotic behavior is revealed: the region of stability of the suspended object is related to a strange attractor. We discuss possible applications of the present 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.
