| Abstract | The performance of the fuzzy logic controller (FLC) is better under transient conditions, while that of the proportional plus integral (PI) controller is superior near the steady-state condition. The combined advantages of these two controllers can be obtained with hybrid fuzzy-PI speed controller. The computations involved with the FLC are much higher as compared to that of the PI controller. Generally, the FLC output is near the maximum permissible value at the beginning of a transient condition but reducing with the reduction in the speed error. In this paper, instead of the FLC, a fuzzy equivalent proportional (FEP) controller is used along with the PI controller to make it a hybrid PI (HPI) controller which eventually is much faster and less computation intensive. The performance of the vector-controlled permanent magnet synchronous motor drive with this HPI controller is obtained with six switching functions, namely: 1) saturation; 2) hyperbolic tangent; 3) polynomial S function; 4) output of FEP controller only; 5) output of PI controller only; and 6) combination of the outputs of both the PI and FEP controllers. From the results, it is observed that the polynomial S switching function based HPI controller is better in general for most of the performances. |

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.
