| Abstract | Magnetic levitation power supply (MLPS) is an onboard electrical installation for electromagnetic suspension (EMS) type maglev train, which can provide the energy for suspension control systems on board. Essentially, the MLPS is a special high power DC-DC switching power supply, whose power is usually more than 50 kW. As the load characteristic is variable and complex, there is a great difficulty for the controller to maintain constant output voltage. After the load of MLPS is modeled, a self-adaptive PID algorithm is proposed to minimize the output voltage ripple and increase its regulating rate of output current. The parameters of PID controller can be adjusted online, as the error of the output voltage varies. It is proved that the proposed method will highly enhance the reliability of MLPS and quality of the magnetic levitation system. |

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.
