| Abstract | In this paper we consider the flight-trajectory tracking problem of an input-disturbed non-minimum phase vertical takeoff and landing (VTOL) aircraft with delayed attitude measurements. By applying the first-order Padé approximation method to deal with the time delays, the problem is reduced to the output tracking of a new high-order non-minimum phase system without delay, whose dynamics are then separated into minimum-phase and non-minimum-phase parts. By using Devasia's stable noncausal inversion method, the ideal internal states of the non-minimum-phase subsystem are obtained and two error subsystems are ultimately constructed. We propose two low-dimensional sliding mode controllers to stabilize the error subsystems, which can render the overall closed-loop system stable in spite of the existence of disturbances. Simulations are performed to show the main results of this paper. |

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.
