| Abstract | Autonomous vehicle systems have been the topic of much research due to their ability to perform dangerous, repetitive and automated tasks in remote or hazardous environments. The potential for multi-vehicle systems cooperating together to accomplish given tasks is starting to draw together researchers from several fields, including robotics, control systems, and computer science. Multiple vehicles can be more effective than a single one, for example in information gathering tasks. By spreading out over the terrain to be searched, a cluster of autonomous helicopters, for example, can locate a target quite rapidly, or a group of coordinated autonomous underwater vehicles can search a coastal area for mines. In other cases, the coordinated operation of multiple vehicles can provide new capabilities. This is the case, for example, of the PATH strategy of platooning several vehicles as they travel along the highway, which may yield up to a four-fold increase in transportation capacity while enhancing safety. Another example is the Mobile Offshore Base, where semi-submersible modules are aligned to form a military base and runway at sea. The unprecedented length of the at-sea runway (up to a mile long) warrants the use of several modules. In each of these cases, there is a need for inter-vehicle communications so that each vehicle can know the status of the operation, the position of its counterparts, and whether the specific mission goals have changed. Thus the control and communication problems become inexorably tied. However, few results are available to analyze performance and stability of a closed loop system where some of the loops are closed by communicated variables. Using the above examples as a motivation, this paper examines emerging results in networked multi-vehicle systems. Recent work has taken many different approaches, such as hybrid systems, distributed control, differential games, control architectures, and artificial intelligence. The focus of this paper is on the control systems perspective. We attempt to present some current issues common to networked multi-vehicle systems, and to show how they have been solved to date in the perspective of the case studies. |

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.
