Contribution à l'architecture, la modélisation et la commande d'un bras manipulateur aérien

Abstract : Unmanned aerial vehicles (UAVs), progressively used by different military and commercial tasks, have the possibility to move in a 3D environment in Cartesian coordinates to assist humans, inspect dangerous areas or photography. Some of these missions require contact with the environment, such as handling objects in flight. In order to accomplish this kind of mission, that thesis made it possible to consider and design a dual system consisting of a manipulator arm connected to the base of a multirotor. The main problem resulting from this new structure involves the ability to stabilize the mechanism concurrently with a permanent change in its inertia due to the movement of the manipulator. In this manuscript, a new concept of the aerial manipulator is proposed, capable of stabilizing the system with the implementation of a prismatic joint to operate the center of gravity of the whole system while keeping it as close as possible to the vertical axis. A further contribution in this study, when a new classification of aerial manipulation systems based on a symbolic formula is introduced, capable of specifying the type and number of multirotors and manipulators used within the mechanical structure. A new algorithm for calculating the solutions of the inverse geometric model, based on an analytical approach, is thus developed and compared to iterative algorithms presented in the literature. The dynamic model of the overall system is obtained by the use of symbolic mathematical tools and functions developed in this project. Two modeling methods, coupled and decoupled, have been introduced. The control part is designed for a coupled system using three control laws and applied to various scenarios, each consisting of multilayer blocks (trajectory planning, internal layer of position and attitude control, control block of virtual entry). Different values of the angles of the manipulator arm joints are analyzed and tested for the efficiency of the prismatic joint. Three approaches to the interaction of the end organ of the robotic arm with the environment are implemented and simulated. A case study and the application of the control impedance module are simulated. Finally, the approaches and methods implemented in this thesis are validated using a virtual prototype in the SimMechanics environment, where a graphical user interface GUI is designed to manipulate and visualize the system during programmed scenarios, thus demonstrating the interest of the main thesis contributions.
