| Abstract | Controller design for magnetic levitation systems is considered to be difficult due to uncertainties and nonlinearities which existed in the system. The plant has inherently strong nonlinearities due to the natural properties of magnetic fields. Also the external disturbances will deteriorate the dynamic performance of the magnetic levitation system, and may give rise to system instability. These problem triggers enormous interests in designing various controllers for the non-linear dynamic system. Designing and implementing controllers for such systems is a meticulous work. In this paper, the robust QFT controllers and prefilters are designed using Interval Constraint Satisfaction Problem based method. The robust controller is designed by solving quadratic inequalities of robust stability and performance specifications. In QFT, the prefilter is designed to achieve the desired tracking specifications. The prefilter is designed by solving the quadratic inequalities of upper and lower tracking specifications. In this paper, the designed QFT controllers and prefilters are tested on the experimental setup designed by Educational Control Product Magnetic Levitation Setup ECP 730. |

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.
