| Abstract | Water delivery canals are large, spatially distributed structures whose objective is to bring in a continuous way water from the sources to the points were it is used. Due to their large scale character, the backbone of water delivery canals modeling is made of partial differential equations, in particular the Saint-Venant equations that embody mass and moment conservation. As a consequence this type of plants have an infinite dimension and are difficult to control due to phenomena like wave formation and a strong interaction between different parts. In this work, a canal made of four sequential pools is considered, the gates between adjacent pools being the actuators. In order to tackle the above dynamic characteristics, in particular the strong interaction between canal subsystems, a distributed model predictive control (MPC) algorithm is used. As such, the controllers driving each gate communicate with each other in order to make coordinate moves. The resulting algorithm is a sub-optimal version of a centralized, multivariable, MPC controller. The paper presents the distributed MPC algorithm applied to the canal and shows that it is a near optimum approximation. |

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.
