| Abstract | The aim of an observer (virtual sensor) is to estimate a special variable from available information and a system model. The vehicle sideslip angle and velocity of the centre of gravity (Vg) are the important parameters in the vehicle stability control system. Extended Luenberger observer, extended Kalman filter and sliding-mode observer (SMO) are the widely used to observe the two parameters. Chattering is usually caused by a sign function in the SMO, so a hyperbolic tangent switching function is used instead of the sign function to overcome the chattering problem in this paper. The SMO with the hyperbolic tangent switching function is used to estimate the tire-road forces, and then the sideslip angle and Vg are calculated using the single-track model. The accuracy and robustness of the proposed observer are proved by the results of the simulator ve-DYNA under different conditions. |

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.
