| Abstract | A formulation of the Loop Transfer Recovery (LTR) design problem using an $ξ_{∞}$ (sub-) optimality criterion is presented in this paper and state space formulae are given as its solution. The LTR problem is formulated as an $ξ_{∞}$ norm constraint for a recovery error which can be defined in two ways: either as a recovery error of the sensitivity function or as a recovery error of the input-output transfer function. Applying output feedback controllers we proceed from the recovery errors to an $ξ_{∞}$ state space formulation. The control problems corresponding to the two recovery error types are given as two different $ξ_{∞}$ state space problems. Each $ξ_{∞}$ problem is decomposed into the well known regular problem and a totally singular problem. The dynamics of the obtained controllers are at most of order 2n. Moreover, the $ξ_{∞}/LTR$ method handles both minimum phase as well as non minimum phase systems in a common framework. |

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.
