| Abstract | The author addresses the problem of stabilizing an unstable time-invariant discrete-time linear system by means of state feedback when the measurements of the state are quantized. It is found that there is no finite-memory control strategy which stabilizes the system in the traditional sense of making all closed-loop trajectories tend asymptotically to zero. If the system is not excessively unstable, however, one can implement feedback strategies which bring closed-loop trajectories arbitrarily close to zero for an arbitrarily long time. If the system is too unstable to apply these control laws, it is found that when ordinary linear feedback of quantized state measurements is applied, the resulting closed-loop system exhibits qualitative behavior which is chaotic. When the state is one-dimensional, a quantitative statistical analysis of the resulting closed-loop dynamics reveals the existence of an invariant measure on the state space which is absolutely continuous with respect to Lebesgue measure and with respect to which the closed-loop system is ergodic.< |

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.
