This thesis proposes novel vision-based controllers for the guidance of Unmanned Aerial Vehicles (UAVs). It considers scenarios involving both single and multiple vehicles. For the case of a single-vehicle, novel Image-based visual servo control (IBVS) approaches are proposed for both fixed-wing and vertical take-off and landing (VTOL) UAVs operating in urban or congested environments. Navigation tasks in a complex environment with obstacle avoidance capabilities are considered. In particular, the landing of fixed-wing UAVs on an airstrip and the landing of VTOL-UAVs that includes an obstacle avoidance strategy are considered. The originality of the study lies in the direct exploitation of the centroid of the image of the observed pattern together with the optical flow, thereby eliminating the need to estimate the position and the velocity of the UAV.For multiple vehicles, novel bearing formation controllers are designed for formations under both directed and undirected interaction topologies. Optical flow is explored in the bearing formation control laws in order to achieve collision avoidance between different agents during the formation progression.In order to relax the classical conditions required by bearing rigidity theory and to lift the scale ambiguity caused by bearings, persistence of excitation of the desired bearing reference is explored. The proposed methodology is supported by rigorous mathematical tools (This involves nonlinear dynamical systems and analysis using Lyapunov theory to formally prove the asymptotic (or exponential) stability of the system, guarantee robustness, and finally ensure good performance of the closed-loop system). Further support is provided by real experiments and/or simulation results

The visual servo control technology is based on measurements form a camera. This technique appeared in the late 80’s to control mobile robots or manipulators. Recently, visual servoing is applied to flying vehicles, for which this type of control has a strong operational potential. In this thesis, we focus on the design of visual servoing for two types of flying vectors : the VTOL minidrones and fixed-wing aircrafts. We try wherever possible to specify the problem in terms of regulation in the picture by taking into account the limitations of the sensors used. Thus we consider only the onboard sensors autonomous, and whose quality is consistent with a the considered visual servoing tasks. For this, we propose visual servoing laws adapted to the considered systems intheir control structures and their measurement systems. For VTOL minidrones, a series of control laws is proposed to stabilize the vehicle with respect to a relativity flat target which some landmarks are detected in real time. These commands have the distinction of not requiring measurements of the speed of translation. This characteristic is especially interesting, since this variable is particularly difficult to measure without GPS. One of the algorithms has been, validated in fight ion the platform. HoverEye developed by Bertin Technologies, it was, to our knowledge the first image based visual servoing, conducted indoors on a minidrones. For fixed-wing aircrafts, a next autonomous landing technique based on the detection of runway’s edges is proposed. This technique is image based and takes into account the specificities of aircraft flight dynamics. Moreover a specific estimate of cross-wind is proposed. Validation of this approach is performed on a complex simulator which includes images processing. Finally, we sought new applications in image based visual servoing for fixed-wing aircrafts. A control law for precise stabilization on observation orbit has been synthesized. It is based on the detection of a single landmark and translational optical flow. Simulations illustrate the performance of that algorithm

In 2022, the legislature adopted a framework authorising the use of aerial drones equipped with cameras by law enforcement agencies and emergency services. These airborne cameras have been added to the arsenal of video-protection systems and become part of the debate on surveillance of public spaces. In fact, the mobile and aerial qualities of public safety drones increase the restrictions to the right to privacy. In addition, the data processing they perform constitutes an interference with the right to protection of personal data. Today, their possible association with video analytics to help law enforcement agencies make decisions is raising new issues at a time when artificial intelligence software does not yet benefit from an appropriate legal framework. As this technology is not infallible, decisions taken on the basis of the algorithm's results could lead to arrests or even arbitrary detention. The aim of this thesis is therefore to examine the changing relationship between personal security and public safety in the context of 'augmented' aerial drones for public safety. The study analyses the impact of the use of this technology on rights and freedoms, before looking at the possible strengthening of their guarantees in the era of 'augmented' public safety surveillance technologies

Now days, the interest for the small size Unmanned Aerial Vehicle (UAV) area is very important. In order to lead inspection and recognition missions, the French Atomic Energy Commission (CEA) is interested in the use of a rotary wings aerial vehicle suited for quasi-stationary flight conditions. Consequently, a prototype ideally suited for this type of mission and for stationary fight conditions, known as an "X4-flyer" has been built. This kind of small aerial robot is known from the modelist and can be bought as a toy. However, it is very difficult to control it without a lot of hours of traning. Consequently, this document presents several embedded algorithms allowing the simple control of the vehicule from simple user translational speed orders. Then, image-based visual servo controls, computed on a ground station, are equally presented and allow the stabilization of the UAV above a target situated on the ground. In order to do this, in a first time, we are interested in the understanding of the different aerodynamical effects applying on the "X4-flyer" and to the elaboration of a mathematical model of the vehicule. Then, a state feedback and a non linear adaptative control, easy to on board and based on the precedent model, are designed. This control law take into account the model non linearity. At least, 3D visual servoing and 2D visual servoing derived for the full dynamics of the system is designed. Each theoretical part of the document has been tested and validated on the experimental UAV

This thesis deals with the development of a compact microphone array and a dedicated signal processing chain for aerialtarget recognition and direction of arrival (DOA) estimation. The suggested global approach consists in an initial detection ofa potential target, followed by a DOA estimation and tracking process, along with a refined detection, facilitated by adaptivespatial filtering. An original DOA estimation algorithm is proposed. It uses the RANSAC algorithm on real-time time-domainbroadband [100 Hz - 10 kHz] pressure and particle velocity data which are estimated using finite differences and sums ofsignals of microphone pairs with frequency-dependent inter-microphone spacings. The use of higher order finite differences, or variants of the Phase and Amplitude Gradient Estimation (PAGE) method adapted to the designed antenna, can extend its bandwidth at high frequencies. The designed compact microphone array uses 32 digital MEMS microphones, horizontally disposed over an area of 7.5 centimeters. This array geometry is suitable to the implemented algorithms for DOA estimation and spatial filtering. DOA estimation and tracking of a trajectory controlled by a spatialization sphere in the Ambisonic domain have shown an average DOA estimation error of 4 degrees. A database of flying drones acoustic signatures has been set up, with the knowledge of the drone’s position in relation to the microphone array set out by GPS measurements. Adding artificial noise to the data, and selecting acoustic features with evolutionary programming have enabled the detection of an unknown drone in an unknown soundscape within 200 meters with the JRip classifier. In order to facilitate the detection and extend its range, the initial detection stage is preceded by differential beamforming in four main directions (north, south, east, west), and the refined detection stage is preceded by MVDR beamforming informed by the target’s DOA

In this thesis, we address the 3D flight control problem for small unmanned aerial vehicles. The first step in achieving such UA V autonomy is basic stability. In doing so, we investigate control techniques which would allow a small rotorcraft UA V to perform autonomously basic tasks such as take-off, hovering and landing. The proposed flight controllers consider actuator saturation and guarantee system stability and good flight performance. One of the main contributions of this thesis is also the development of a vision-based autopilot for self localization, obstacles detection and control of small autonomous helicopters using optic flow and inertial data. The proposed autopilot is inspired by insects and represents a major step toward our goal of designing autonomous small flying machines capable of navigating within urban and unknown environments. It is composed of a vision module for localization and perception, and an adaptive control system for navigation and trajectory tracking

Nowadays, we see a growing popularity of the use of Unmanned Aerial Vehicles (UAV) ofespecially Vertical Take-Off and Landing (VTOL) type. One of the most known VTOL is thequadrotor or Quadcopter which is probably the most used one as a research platform. Thisthesis deal with attitude control and estimation techniques applied to a rigid body movingin 3D space such as Quadcopter VTOL. The first contribution of this thesis is the design ofa new class of complementary linear-like filters allowing the fusion of inertial vector measurementswith angular velocity measurements and combined with algebraic algorithms asTRIAD, QUEST etc. to give an efficient attitude estimation solution. This class of filtersallows several possibilities of implementation such as the order of the filters which can bechosen high in order to reduce more the measurement noise and the form of the filters thatcan be direct or passive and the ability to take into account the possible gyro bias. Lyapunovanalysis shows the global asymptotic convergence of the estimation errors to zero. The sameprinciple of data fusion is used for the proposed new attitude control law in which the complementaryfilters were included to reduce the effect of measurement noise. The obtainedcontroller ensures almost global stability of the desired equilibrium point; it represents thesecond contribution of this thesis. The third contribution takes into consideration an interestingspecial case, where instantaneous measurements of attitude and angular velocity areunavailable. A first order linear auxiliary system based directly on vector measurements isused in an observer-like system to handle the luck of angular velocity. The proposed controllerensures almost global asymptotic stability of the trajectories to the desired equilibriumpoint. Detailed sets of experiments were done to validate the obtained results
