| Abstract | This paper deals with consecutive (open-loop) identification and (closed-loop) control of a linear, time-invariant SISO process. The partition of a fixed total time between identification and control. is optimised according to an LQ criterion. For a static gain process, an analytical expression for the optimal identification time as a function of the a-priori parameter mean and variance is derived. For an integrator process, the optimal identification time obtained from simulations is approximated by an analytical formula. Both procedures are applied on-line by replacing the a-priori statistics by their estimates. Finding an analytical expression for higher order processes appeared infeasible. Therefore, for a static gain process, at each sampling instant, the predicted cost for continuing identification is compared to the predicted cost for starting control This procedure is expected to be applicable for dynamic systems of high order. |

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.
