| Abstract | This paper describes the development and application of a nonlinear fin mixer to control aerodynamic vehicles during demanding flight maneuvers. Maneuvers that may be experienced by a bank-to-turn homing missile utilizing a proportional navigation guidance scheme often drive fin actuators into acceleration, rate and/or position limitations For vehicles where each fin is used to control multiple degrees-of-freedom, these saturations can lead to vehicle instability. This paper explores these regions of instability and develops a nonlinear fin mixer which utilizes information on the actuator limitations to eliminate these instabilities in an optimal manner. The paper presents an implementation of the nonlinear fin mixer in terms of a set of parallel dynamic systems and relates this implementation to that of an Artificial Neural Network. The improvements due to the implementation of the nonlinear mixer are demonstrated using a nonlinear Monte Carlo simulation of a bank-to-turn homing missile pursuing a maneuvering ground target. |

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.
