| Abstract | In this paper, an estimate method of control system measurement error variance for Kalman estimator at run-time is proposed. In general, control system's measurement error variance is measured by some measuring instruments or tuned after implementation of Kalman estimator, but the precise measuring the control system measurement error variance is too hard. Moreover, even though we could tune the measurement error variance value, it could not deal with changes of system measurement error variance because of the phenomena of aging of system sensors or unpredictable external disturbances. So we introduce a method to estimate measurement error variance of the system for Kalman estimator at run-time to improve the performance of the estimator. Also a simple simulation and experimental result will be presented to show the effect of the proposed method. |

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.
