| Abstract | This paper addresses the design, analysis and evaluation of an adaptive feedback-based stable damage detection scheme applied to an aircraft system with structure damage and parameter uncertainties. An aircraft system damage model is presented which captures the key feature of the longitudinal and lateral-directional dynamic coupling caused by the aircraft structure damage. Two detectors are used to estimate decoupled nominal system parameters and coupled damaged system parameters. Unlike most fault detection schemes which operate under the assumption that all system signals remain bounded under damage conditions, the adaptive damage detection scheme proposed in this paper is equipped with an adaptive feedback controller which is designed to ensure the desired signal bound-edness condition needed for stable damage detection operation. By comparing estimation error residuals between the state signals of detectors and that of the aircraft system, system damage is detected. Desired adaptive damage detection performance is demonstrated by extensive simulation results from an application to a high-fidelity aircraft model — the nonlinear NASA Generic Transport Model (GTM) under wing damage conditions. |

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.
