| Abstract | This brief presents the design of a fractional-order (FO) PIλDμ controller and its application to stabilizing an FO solid-core magnetic bearing (MB) system. A practical numerical search method of designing the FO PIλDμ controller is proposed. By presearching the orders λ and μ in their calculated ranges, the remaining three undetermined controller parameters can be first analytically solved based on three given basic specifications, and thus, a series of controllers are obtained. Then, a relative optimal FO PIλDμ controller is achieved by evaluating exact performance indexes. In addition, an integer order (IO) PID controller based on the same specifications is derived and the corresponding feasible control zone consisting of specifications is calculated. The performance comparisons between the IO PID and the FO PIλDμ controllers are implemented by simulation and experiments. The results show that this tuning method is effective, and the FO PIλDμ controller can achieve more favorable dynamic performance than the IO PID controller for this FO MB 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.
