| Abstract | This paper presents a robust nonlinear method for controlling depth and head of Autonomous Underwater Vehicles. The control of autonomous underwater vehicles (AUV) presents a number of unique and formidable challenges. AUV dynamic is highly nonlinear, coupled, time varying and subject to hydrodynamic uncertainties and external disturbances. For trajectory tracking, the problem statement requires the design of a depth and head control system for the vehicle in order to achieve precise trajectory. This paper is presented an adaptive-sliding mode controller focused on self-tuning when the control performance degrades during the operation due to model uncertainties and change in the vehicle system and its environment. The adaptive-sliding mode controller combined advantages of sliding mode controllers and adaptive estimators. In the adaptive-sliding mode controller, robust controller is applied for tracking and rejecting disturbances and adaptive estimator is applied for estimating uncertain parameters. This controller is compared with other control methods such as sliding mode controller. To show the validity of the proposed algorithm, computer simulation results are presented. |

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.
