Повний текст джерелаThe works of this thesis are focused on the control and command of a fleet of many vehicles (4 to 10 vehicles). A longitudinal control is proposed based on the decentralized global approach, for which the information of the leader and the predecessor are assumed to be available to compute the control law using a linearization control by inverse dynamics. This control concept allows to follow a reference speed imposed by the leading vehicle, while respecting a safety distance (variable and constant) to avoid collisions. The longitudinal control is coupled with the lateral control that uses a sliding mode approach to follow the leader's desired trajectory. In addition, different sliding mode observers are developed. These observers are intended to calculate the nonlinear dynamics in the controls of each vehicle. The fleet is treated secondly in the multi-lane trajectories (line configuration). Two control approaches are proposed to control the vehicles in the different lanes (three lanes: i, j and k). The vehicles are controlled in the first strategy to follow the speed of the leader. However, in the second approach, the desired speed of the leader is modified when a lateral movement is present in order to respect the fleet notion. The vehicles are also controlled to avoid obstacles and switch to the next lane by generating an obstacle avoidance trajectory that takes into account the safety distance between the vehicles and the obstacle, and between the vehicles themselves

Повний текст джерелаIn this thesis are investigated methods to manage shared electric autonomous taxi urban systems under online context in which customer demands occur over time, and where vehicles are available for ride-sharing and require electric recharging management. We propose the heuristics based on problem decomposition which include road network repartition and highlighting of subproblems such as charging management, empty vehicle redistribution and dynamic ride-sharing.The set of new methods for empty vehicle redistribution is proposed, such as proactive, meaning to take into account both current demand and anticipated future demand, in contrast to reactive methods, which act based on current demand only.We provide the reinforcement learning in different levels depending on granularity of the system.We propose station-based RL model for small networks and zone-based RL model, where the agents are zones of the city obtained by partitioning, for huge ones. The complete information optimisation is provided in order to analyse the system performance a-posteriori in offline context.The evaluation of the performance of proposed methods is provided in set of road networks of different nature and size. The proposed method provides promising results outperforming the other tested methods and the real data on the taxi system performance in terms of number of satisfied passengers under fixed fleet size

Повний текст джерелаIn recent years, the emergence of new technologies such as miniaturization of components, wireless communication devices, increased storage size and computing capabilities have allowed the design of increasingly complex cooperative multi-agent systems. One of the main research axes in this topic concerns the formation control of fleets of autonomous vehicles. Many applications and missions, civilian and military, such as exploration, surveillance, and maintenance, were developed and carried out in various environments. During the execution of these tasks, the vehicles must interact with their environment and among themselves to coordinate. The available communication tools are often limited in scope. The preservation of the connection within the group then becomes one of the objectives to be satisfied in order to carry out the task successfully. One of the possibilities to guarantee this constraint is the training displacement, which makes it possible to preserve the distances and the geometrical structure of the group. However, it is necessary to have tools and methods for analyzing and controlling these types of systems in order to make the most of their potential. This thesis is part of this research direction by presenting a synthesis and analysis of multi-agent dynamical systems and more particularly the formation control of autonomous vehicles. The control laws developed in the literature for formation control allow to carry out a large number of missions with a high level of performance. However, if a fault/failure occurs in the training, these control laws can be very limited, resulting in unstable system behavior. The development of fault tolerant controls becomes paramount to maintaining control performance in the presence of faults. This problem will be dealt with in more detail in this thesis and will concern the development and design of Fault tolerant controls devolved to a fleet of autonomous vehicles according to different configuration/structuring

Повний текст джерелаUnmanned vehicles are defined as autonomous entities with no operator on board. They are a part of a global system called Unmanned System which also includes elements such as a control station. These vehicles are designed to fulfil the requirements of assigned missions and can be deployed in spatial, aerial, terrestrial and maritime environments. Since a mission cannot be accomplished with a single vehicle, vehicles have to cooperate in order to achieve a global mission. However, cooperation requires communication interoperability between all vehicles. Even if previous works have standardized application protocols, it is not sufficient to ensure data delivery between all vehicles, since they have a specific mobility pattern and sometimes different network interfaces. The main goal of this thesis is to offer a seamless network, including all kinds of unmanned systems. We propose a cross layer approach in order to route and deliver data to any vehicle. In this context, each vehicle is able to transmit data to another without information on the global topology. We have developed a routing protocol, which adapts its strategy, according to the contextand to the network environment. In addition, we exploit the any cast diffusion technique based on vehicles features in order to adopt an optimal routing scheme

Повний текст джерелаTo be able to navigate autonomously, a vehicle must be accurately localized relatively to all obstacles, such as roadside for lane keeping and vehicles and pedestrians to avoid causing accidents. This PhD thesis deals with the interest of cooperation to improve the localization of cooperative vehicles that exchange information. Autonomous navigation on the road is often based on coordinates provided in a Cartesian frame. In order to better represent the pose of a vehicle with respect to the lane in which it travels, we study curvilinear coordinates with respect to a path stored in a map. These coordinates generalize the curvilinear abscissa by adding a signed lateral deviation from the center of the lane and an orientation relative to the center of the lane taking into account the direction of travel. These coordinates are studied with different track models and using different projections to make the map-matching. A first cooperative localization approach is based on these coordinates. The lateral deviation and the orientation relative to the lane can be known precisely from a perception of the lane borders, but for autonomous driving with other vehicles, it is important to maintain a good longitudinal accuracy. A one-dimensional data fusion method makes it possible to show the interest of the cooperative localization in this simplified case where the lateral deviation, the curvilinear orientation and the relative positioning between two vehicles are accurately known. This case study shows that, in some cases, lateral accuracy can be propagated to other vehicles to improve their longitudinal accuracy. The correlation issues of the errors are taken into account with a covariance intersection filter. An ICP (Iterative Closest Point) minimization algorithm is then used to determine the relative pose between the vehicles from LiDAR points and a 2D polygonal model representing the shape of the vehicle. Several correspondences of the LiDAR points with the model and different minimization approaches are compared. The propagation of absolute vehicle pose using relative poses with their uncertainties is done through non-linear equations that can have a strong impact on consistency. The different dynamic elements surrounding the ego-vehicle are estimated in a Local Dynamic Map (LDM) to enhance the static high definition map describing the center of the lane and its border. In our case, the agents are only communicating vehicles. The LDM is composed of the state of each vehicle. The states are merged using an asynchronous algorithm, fusing available data at variable times. The algorithm is decentralized, each vehicle computing its own LDM and sharing it. As the position errors of the GNSS receivers are biased, a marking detection is introduced to obtain the lateral deviation from the center of the lane in order to estimate these biases. LiDAR observations with the ICP method allow to enrich the fusion with the constraints between the vehicles. Experimental results of this fusion show that the vehicles are more accurately localized with respect to each other while maintaining consistent poses

Повний текст джерелаThe 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

Повний текст джерелаThis thesis deals with the issues related to the vehicles fleet renewal. It presents de context, motivations and factors to consider in the renewal process. Decisions-making tools to support the development of the renewal plan, the selection of new vehicles and fleet maintenance management are proposed. The thesis also refers to the cost to consider throughout the life cycle of each vehicle. The contents of this thesis should prove useful to both fleet managers and researches interested in costs analysis with regard to the life cycle of vehicles within a perspective of sustainable development.
