Abstract | This paper investigates the distributed finite-time consensus tracking problem for a group of autonomous agents modeled by double-integrator dynamics under a leader with non-zero acceleration. First of all, a distributed finite-time consensus tracking protocol is proposed based on the relative position and relative velocity measurements. By using a Lyapunov function, it is shown that distributed consensus tracking can be achieved in finite time under the condition that the acceleration of the leader is bounded but not available to followers. In particular, the settling time can be estimated efficiently by computing the value of the Lyapunov function at the initial point. Then, a new observer-based algorithm is designed to solve the finite-time consensus tracking problem when the relative velocity measurements are not available to the agents. It is proved that the states of the followers can move to that of the leader in finite time if the network topology is undirected among the followers but has a directed path from the leader to each follower. Finally, the effectiveness of the algorithms is illustrated by numerical simulations. |

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.
