| Abstract | We consider a class of non-standard networked control problems where (i) there is a limit on the number of times control signals can be transmitted to the plant, and (ii) the links over which the transmission takes place are lossy in the sense that there is a nonzero probability with which packets carrying control signals are dropped. The framework is that of discrete-time LQG optimal control where the control has access to noisy state measurements, and the objective is minimization of the expected value of a quadratic performance index under the nontraditional constraints introduced above. When there is a limitation on the number of control actions, we show that the optimal policy involves thresholding the optimal estimate of the state. When there is also a lossy link, and the control is allowed to receive acknowledgements from the plant as to whether the transmitted packets were received or not, we show that the optimal policy is again of the threshold type, involving off-line computation. |

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.
