| Abstract | This paper proposes a new structure of module suspension system of Electromagnetic System (EMS) maglev train, and presents an active fault-tolerant control method via control law reconfiguration. Being different with conventional module suspension system, the new structure has four controllers which increase the redundancy degree of the system. And CAN network is adopted to transmit signals from sensors. Thus, each controller could obtain adequate information about the system states. Then, current loop is designed for each electromagnet based on cascade control theory. After that, the mathematical model of systems with different control channel failures are constructed and optimal controller is designed for each model. Though simulation, the new structure and its active fault-tolerant control method are proved to be more effective than the conventional method and worthy of using for reference to improve the reliability of suspension system of maglev train. |

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.
