Abstract | In this paper, we study the problem of receding horizon control of spatially distributed systems with arbitrary interconnection topologies. The key idea is the introduction of spatially decaying operators (SD) which serve as the main ingredient in the cost function that couples the state and control of individual agents with those of others. It is shown that coupling between subsystems of many well-known spatially distributed systems such as some of the recently studied models of distributed motion coordination with nearest neighbor interactions as well as spatially invariant systems can be characterized using such operators. We prove that for spatially distributed systems with input and state constraints in which the coupling is through an SD operator in a finite horizon cost function, optimal receding horizon controllers are piecewise affine (represented as a convolution sum plus an offset). More importantly, we prove that the kernel of each convolution sum decays exponentially in the spatial domain, thereby providing evidence that even centralized solutions to the receding horizon control problems for such systems has an inherent spatial locality. Our theoretical results are verified by numerical simulations |

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.
