| Abstract | A derived optimal control law based on optimizing a finite horizon (N) linear quadratic (LQ) criterion at time k for a discrete-time system only yield N time varying feedback gains independent of time k and thus is of an open-loop nature. Applying such a control law at each time iN, i=0, 1, . . ., naturally leads to an N-periodic closed-loop controller called the periodic receding horizon controller. Its closed-loop asymptotic stability and performance properties are studied. Several sufficient conditions for closed-loop asymptotic stability are obtained, one of which, in particular, is weaker than that the solution of the associated Riccati difference equation (RDE) is monotonically nonincreasing and can be rendered satisfied by suitable choice of the initial condition of the RDE. The evaluated infinite time performance of both the periodic receding horizon controller and the receding horizon controller is proved to converge to the optimal one related to the infinite time regulator problem as the horizon N tends to infinity.< |

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.
