| Abstract | In this paper, a flight control and guidance method for a scaled-down quad tilt prop personal air vehicle (PAV) is presented through simulations and flight tests. The developed scaled-down PAV does not fully transit into a fixed-wing flight mode, but longitudinally tiltable nacelles are used to control the longitudinal translation speed. This design concept can realize a flight maneuver with minimized attitude change because it is only necessary to tilt the nacelles of the propellers and not the attitude angle of the whole body. Although controls of a similar tilt-rotor and quad-tilt vehicles have been reported, a research on a guidance algorithm of a vertical take-off and landing (VTOL) PAV is deficient. Therefore, this paper focuses on the guidance algorithm for the quad tilt prop PAV that requires minimized fluctuation for a passenger. The dynamic behavior and responses of attitude and velocity controllers are identified with reasonable accuracy for a simulated test. Using this model, a guidance algorithm is developed for a circular path to minimize variation of a control input and system states. Through the simulated evaluation against the widely-used proportional navigation guidance algorithm, it was found that the proposed circular path guidance method has better performance in terms of total variation. In addition, through the flight test, the feasibility of the current concept for using the propeller nacelle tilt angle as a control input in forward speed control of a quad tilt prop PAV is proved. |

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.
