| Abstract | This study proposes an integral sliding mode control (ISMC) scheme for a class of uncertain non-linear systems subject to actuator faults including outage. It is noted that traditional ISMC method cannot handle actuator outage. To tackle the problem, matrix full-rank factorisation technique and adaptive mechanism are incorporated. Based on the above technique, two novel integral sliding surfaces using construction methods I and II are then introduced and existence conditions of sliding modes are given in terms of linear matrix inequalities, in which less conservativeness and better robustness against actuator faults are obtained using construction method II than I. The fuzzy logic systems are applied to approximate the bounds of unknown non-linear functions. Furthermore, an integral sliding mode controller, without an fault detection and isolation mechanism, is synthesised to guarantee the asymptotic stability and the robustness of the closed-loop system against actuator faults and non-linearities from the every beginning. Finally, simulation results for a model of B747-100/200 aircraft confirm the effectiveness of the proposed control method. |

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.
