Abstract | This paper presents a sliding mode disturbance observer-based constraint backstepping control approach (CBS/SMDO) to control a cargo aircraft during heavy cargo airdrop operation. The CBS/SMDO controller is capable of dealing with parametric uncertainties, external disturbances, and unmodeled dynamics in the presence of state/control constraints. The super-twisting second order sliding mode disturbance observer (SOSMDO) is utilized to compensate for the overall uncertainties, avoiding high control gains. The SOSMDO is much simpler than the neural networks-based estimator and could provide asymptotic convergence of the estimation error to zero in finite time. The closed-loop stability is guaranteed in the sense of Lyapunov. The proposed CBS/SMDO controller is applied to the airdrop flight control design on a nonlinear six-degrees-of-freedom transport aircraft model in a low attitude tandem extraction airdrop scenario. Simulation results demonstrate the feasibility of the CBS/SMDO 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.
