Повний текст джерелаThis thesis presents the measurement of geometrical characteristics of spreading vegetation fires with a multimodal stereovision system carried by an Unmanned Aircraft Vehicle.From visible and infrared stereoscopic images, 3D fire points are computed and fire geometrical characteristics like position on the ground, rate of spread, height, length, width, flame tilt angle and surface are estimated.The first important contribution of this thesis is the development of a multimodal stereovision portable drone system. This device integrates cameras working in the visible and infrared domains, a Raspberry Pi computer, electric batteries, GPS receptors and an Inertial Measurement Unit. It allows to obtain georeferenced stereoscopic multimodal images.The second important contribution of this thesis is the method for the estimation of the fire geometrical characteristics from aerial stereoscopic images.The geometrical characteristics estimation framework have been evaluated on a car of known dimensions and the results obtained confirm the good accuracy of the device. It was also successfully tested on an outdoor non propagating fire. The results obtained from vegetation fires propagating on terrain with slope changes are presented in detail

Повний текст джерелаThe dynamic modeling of the autonomous flying machines makes these last decades important strides because of interest that those offer in the military or civil field. This work presents a complete dynamic model which holds account of the flexibility of the structures or components of a Helicopter drone with four rotors, with strong manoeuvrability and having a good stability in hovering, called XSF conceived at the Dataprocesing Laboratory Integrative Biology and Complex System’s (IBISC) of the University of Evry Val Essonne. The XSF is regarded as a system multi bodies with articulated chains, in this direction a first dynamic model is elaborate while being based on the technique of the Lagrange multipliers to take into account the forces of contact between the different ones under structures. By introducing the aerodynamic torques and of gravity, the equilibrium equations are written and solved by using a method of substitution to eliminate the multipliers Lagrange. An algorithm of numerical integration semi-explicit of conditionally stable Newmark is used. With an aim of accelerated numerical integration of the model, a second dynamic model based on the method of the relative co-ordinates, lighter and less expensive in computing times is proposed like alternative and to better adapt for the development of a law of order and the control of flight. The aerolastic phenomenon of coupling on the level of the airfoils of the flexible blades of propellers is taken into account in the variation of the angle of attack which modifies the torque of the aerodynamic loads applied to the system

Повний текст джерелаThe interest of dynamic modeling and control of the autonomous flying objects increased significantly during these last years. Complexity and capability of these flying objects are expanding rapidly now, and the range of missions their designed to support is growing. In order to fulfil this requirement, it is necessary, in one hand, to introduce the effect of the structural flexibility and the aerodynamic phenomenon in the dynamic model, and in the other hand, to build a suitable strategy of command and stabilization for these flying objects. The work is registered within this framework, and relates two types of engines: - Lighter than air vehicle: Application on the modelling and control of flexible airship. - Heavier than air vehicle: Application on the modelling and control of flexible micro-drone. We present a general model of autonomous flexible flying engine undergoing great overall motion and small elastic displacements. The formalism used is based on the Newton- Euler approach, which is frequently used for rigid flying objects. In this study we generalize the existing formalisms for rigid bodies, by including the effect of flexibility without destroying the total methodology. A modal synthesis is used. A hybrid method based on the energetic principles and Lagrange equations is presented. The phenomenon of the added masses is also taken into account. In order to integrate the fluid-structure interaction of a flexible airship, we develop an original analytical formulation of the problem using both the new notion of flexible flow potential, and the development of the kinetic energy of the air constrained by the motion and the vibration of the airship. This method allows to put in an obvious place the coupling "overall motion - flexibility" in the added mass matrix. We also present the dynamic and aerodynamic model of a flexible quadrirotor called XSF, designed in the IBISC laboratory and intended for an interuniversity competition for microdrones. A robust methodology based on the " Backstepping " control is realized to stabilize the airship around a desired position, and a PID controller is proposed to stabilise the XSF. The strategy of command is compelled by imperative to optimize the ratio precision/portability, to allow an easy insertion of the developed algorithms in the embedded electronics. A numerical validation is presented in the end of this report

Повний текст джерелаVTOL (Vertical Takeoff and Landing) flying vehicles are non-linear, unstable and complex systems in particular during quasi-stationary flight mode, they present a strongly coupled dynamics. Thus, we were interested throughout this thesis to the problems of visual servoing and orientation estimation of VTOL robots in order to obtain good performances for their automatic control. The thesis is divided into two parts: We developed a visual servoing control strategy of a VTOL engine in hovering mode. This control law is based on the robust techniques of Backstepping, allowing the limitation of the orientation to small values. Then, we worked out a control law of tracking a predefined trajectory. The direction of the gravity vector exists even in the definition of the visual errors. Therefore, it is crucial to get a precise estimation of this direction vector. We used inertial measurements to elaborate an estimator for the gravity direction and another estimator for an independent direction. From these two directions the orientation matrix was restored. The vector of gyroscope bias is also estimated. Another original aspect of this work is the conception of a third estimator for the total orientation matrix, this estimator guarantees that the matrix of orientation remains in the SO(3) group. The control strategies and the estimators were validated by results from simulations and experiments on the HoverEye vehicle from Bertin Technologies

Повний текст джерелаPrevious research on the visuo-motor system of the fly within the Neurocybernetics Group of the Laboratory of Neurobiolgy, CNRS, Marseilles, France, has led to the development of two mobile robots which feature an analogue electronic vision system based on Elementary Motion Detectors (EMD) derived from thoseof the fly. A tethered Unmanned Air Vehicle (UAV), called Fania, was developed to study Nap-ofthe-Eart (NOE)flight (terrain following) and obstacle avoidance using a motion sensing visual system. After an aerodynamic study, Fania was custom-built as a miniature (35 cm, 0. 840kg), electrically-powered, thrust-vectoring rotorcraft. It is constrained by a whirling-arm to 3 degrees of freedom with pitch and thrust control. The robotic aircraft's 20-photoreceptor onboard eye senses moving contrasts with 19 ground-based neuromorphic EMDs
