| Abstract | This article studies output synchronisation of a set of non-linear interconnected systems and general linear interconnected systems. It will be shown that output synchronisation of the systems can be achieved by adding a new coupling interconnections (consensus algorithm) to the existing interconnections if the input and output relationship of the given system is passive. The output synchronisation scheme will then be applied to a class of interconnected non-linear systems with the special structure of port-controlled Hamiltonian (PCH) dynamics. Since the structure of the PCH systems is restrictive, we further present a synthesis of state feedback controller to overcome the restriction. This result will be applied to multi-machine power systems. As the second part of this paper, the output synchronisation of general linear interconnected systems will be ensured. In the case of linear interconnected systems, the synchronisation can be achieved by a decentralised observer-based output feedback control scheme. The controller and observer gains will be calculated from decentralised linear matrix inequality conditions. Simulation tests are conducted to evaluate the performance of the proposed methods. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
