| Abstract | An H∞ fuzzy trajectory estimation is proposed for robust tracking guidance and early warning in antitactical ballistic missile systems with model uncertainties and external disturbances. In order to avoid solving the nonlinear Hamilton-Jacobi-Isaac(H-J-I) partial differential equation for H∞ trajectory estimation of the nonlinear reentry vehicle (RV) dynamic equation, the Takagi and Sugeno fuzzy linear model is employed to interpolate piecewise to approximate the RV nonlinear dynamic equation. Then, from the fuzzy linear model, a fuzzy H∞ state estimator is developed for robust trajectory estimation of RV with optimal attenuation of the worst-case effect of system uncertainties such as approximation error, external disturbance, maneuver and unpredictable external forces in flight and other sources. The proposed method parameterizes the H∞ trajectory estimation problem in terms of an eigenvalue problem (EVP), so that the worst-case effect of system uncertainties on the trajectory estimation error is minimized in the robust trajectory estimation design subject to certain linear matrix inequality (LMI) constraints. Convex optimization techniques are employed to solve the EVP of the H∞ fuzzy trajectory estimation in antitactical ballistic missile systems. Simulation results indicate that the proposed method possesses a satisfactory performance. |

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.
