| Abstract | Presents a method of exact fuzzy (TSK) modeling and optimal control of the inverted pendulum on a cart, which is a benchmark nonlinear dynamic system. Conventionally, the TSK (Takagi-Sugeno-Kang) fuzzy modeling blends local linear models to represent a nonlinear system, which in general does not exactly represent the nonlinear system under consideration. Here, instead of local linear models, a set of 'boundary linear models' and new membership-functions are defined such that the fuzzy blending of these models result in an exact representation of the overall nonlinear system. The SAM theorem of exact fuzzy representation of a scalar function is extended to a class of nonlinear dynamic system. Optimal fuzzy controller design results based on local linear models could be applied for the optimal fuzzy controller design based on 'boundary linear models' where, the fuzzy blending of these boundary linear models gives rise to an exact fuzzy model of the inverted pendulum on the cart. Optimal control laws are designed for each of these fuzzy subsystems, and overall control is again the fuzzy blending of these individual control laws. This procedure results in optimal control solution for the original nonlinear control problem. Optimal fuzzy controller is designed based on this exact fuzzy model and results are compared with a conventional design. |

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.
