| Abstract | Presents a nonlinear (fuzzy) control structure enhanced with supervised learning and/or adaption. Availability of at least a partial process model is assumed. A nonlinear process identification procedure is used to complete the partial model. Based on the identification model the system sensitivity model is derived which guides the training process to keep the training time (the number of observations) at minimum. The identification model introduced consists of a linear dynamical section (filter) and a nonlinear zero-memory section (implemented by a fuzzy mapping). Only the filter section is on the primary signal path. The nonlinear mapping delivers the filter parameters (depending on the system input and state). An adaption procedure is introduced, which tunes the nonlinear mapping (e.g. membership function parameters) to minimize identification error. The process identification and the controller tuning can run parallel, in this way the online adaption of the controller can be realized in a straightforward way. The scheme proposed can incorporate a priori knowledge on two levels (system topology and fuzzy rule set). The most distinctive features of the scheme are that it directly supports controller design and/or (online) tuning in various ways and results in a dynamical system, which is relatively easy to analyze using well established traditional analysis methods. The identification and control scheme can readily incorporate other types of sufficiently smooth parameterized nonlinearities (e.g. neural networks or domain specific specialized nonlinear mappings). |

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.
