| Abstract | This paper summarizes a finite element analysis (FEA)-based modeling approach and nonlinear control synthesis for a large air gap magnetic levitator. The levitator consists of a 10 mm diameter heteropolar magnetic bearing used to control the position a 2 mm diameter ferromagnetic collar bonded to a flexible microcatheter. The unusually large air gap causes the system to exhibit strongly nonlinear behavior, which is attributed to significant leakage and mutual magnetic flux paths. FEA is used to model these nonlinear flux relationships and derive system state equations. Next, a feedback linearizing controller is designed, and closed-loop system simulations are performed using MATLAB. These simulations demonstrate stability and excellent tracking performance over a range of catheter positions. Steady-state performance is shown to depend on catheter position, with errors of up to 0.1760 mm in response to a 3 mm step input. The time-averaged error in tracking a 3 mm diameter circle is shown to be at most 0.0170 mm. Control strategies which are more robust to model uncertainties and discrepancies are recommended to improve the tracking performance. |

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.
