Abstract | The near space autonomous airship represents a unique and promising solution for many applications ranging from surveillance, communication utilities and scientific exploration. In attempt to complete the various missions, the near space airship first requires an accurate control system for autonomous flight. This paper presents an improved sliding mode control method for autonomous flight, considering the characteristics of nonlinearity, strong coupling and uncertainty of an airship. Firstly, the dimensional motion mathematical model of an airship is derived, including kinematics and dynamics equations. Then the controller for autonomous flight is designed by use of an improved variable structure control method, which adopts the boundary layer sliding mode control approach. Finally simulation results illustrate the effectiveness of the proposed method. The proposed control method is robust to parameter uncertainties and external disturbances, and provides an effective approach to design flight control system of a near space airship. |

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.
