Abstract | This paper considers the problem of reliable H∞ control against actuator failures for linear continuous-time systems. The model including actuator partial failures and actuator lock-in-place failures is presented, and the faults of being locked in place are accurately described as zero-frequency disturbances and their attenuation performances are described by using small gain conditions based on finite frequency approach. Then a two-step LMI-based algorithm is developed for designing reliable H∞ dynamic output feedback controllers. The resulting designs guarantee the stability and disturbance/fault attenuation performances of the closed-loop systems, not only when all control components are operational, but also in case of some actuator failures. Finally, a numerical example is given to illustrate the advantage of the proposed design method in comparison with the entire frequency approach by using bounded real lemma. |

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.
