Texte intégralThe presented work is part of a larger project called SHARE, which consists in developing a universal new generation ground control station for the monitoring and the control of fixed and rotary wing UAVs (Unmanned Aerial Vehicle).The objective of this PhD thesis is to develop a generic ground control station simulator capable of simulating in real time different types of UAVs, onboard sensors, several flight environments, and various military missions which are defined according to the STANAG 4586 standard. First, we introduce the model of the different parts of the station, and then we present the architecture adopted for the simulator and the control module. The latter is divided into several hierarchical levels; the upper level contains the path planning algorithms for fixed wing HALE (High Altitude, Long Endurance) UAV. These algorithms are used to calculate an admissible path between initial and final position by minimizing a cost function.Finally, in order to manage missions online, we developed a decision support system that is capable of performing a variety of objectives. This system also supplies the operator the best paths proposed by planning algorithms. This tool aims to help the station operator to make the decision by maximizing the rewards obtained during the achieving the objectives and minimizing certain criteria (resource consumption, danger, weather,..)
Ašković, Veljko. « Aerial vehicle guidance problem through the Pontryagin Maximum Principle and Hamilton Jacobi Bellman approach ». Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS553.
Texte intégralThis thesis is mainly composed of two parts. In the first part, we investigate the large time behavior of the value function associated to an optimal control problem in the finite dimensional case. We first establish the large time asymptotic expansion in the linear quadratic (LQ) theory. We then generalize this expansion to nonlinear dynamical systems more precisely within the class of dissipative systems. In the second part, we solve numerically the guidance problem of an aerial vehicle. We first model mathematically the equations of motion. Then, we implement three methods in order to solve the problem: a direct method, an indirect method based on the continuation process and the shooting method. Finally, we implement a numerical method derived from the Hamilton Jacobi Bellman theory in order to compute optimal trajectories and at the same time the reachable sets
Rousseau, Gauthier. « Optimal trajectory planning and predictive control for cinematographic flight plans with quadrotors ». Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLC086/document.
Texte intégralThis thesis focuses on the autonomous performance of cinematographic flight plans by camera equipped quadrotors. These flight plans consist in a series of waypoints to join while adopting various camera behaviors, along with speed references and flight corridors. First, an in depth study of the nonlinear dynamics of the drone is proposed, which is then used to derive a linear model of the system around the hovering equilibrium. An analysis of this linear model allows us to emphasize the impact of the inertia of the propellers when the latter are tilted, such as the apparition of a nonminimum phase behavior of the pitch or roll dynamics. Then, two algorithms are proposed to generate smooth and feasible cinematographic trajectories. The feasibility of the trajectory is ensured by constraints on its time derivatives, suited for cinematography and obtained with the use of the nonlinear model of the drone. The first algorithm proposed in this work is based on a bi-level optimization of a piecewise polynomial trajectory, in order to find the fastest feasible minimum jerk trajectory to perform the flight plan. The second algorithm consists in the generation of feasible, minimum time, non-uniform B-spline trajectories. For both solutions, a study of the initilization of the optimization problem is proposed, as well as a discussion about their advantages and limitations. To this aim, they are notably confronted to simulations and outdoor flight experiments. Finally, a predictive control law is proposed to smoothly and accurately control the onboard camera

Texte intégralIn the field of industrial robots, there is a growing need for having cooperative robots that interact with each other and share work spaces. Currently, industrial robotic systems still rely on hard coded motions with limited ability to react autonomously to dynamic changes in the environment. This thesis focuses on providing a novel framework to deal with real-time collision avoidance for robots performing tasks in a dynamic environment. We develop a reactive trajectory generation algorithm that reacts in real time, removes the fastidious optimization process which is traditionally executed by hand by handling it automatically, and provides a practical way of generating locally time optimal solutions.The novelty in this thesis is in the way we integrate the proposed time optimality problem in a task priority framework to solve a nonlinear optimization problem efficiently in real time using an embedded system with limited resources. Our approach is applied in a Model Predictive Control (MPC) setting, which not only improves reactivity of the system but presents a possibility to obtain accurate local linear approximations of the collision avoidance constraint. The control strategies presented in this thesis have been validated through various simulations and real-world robot experiments. The results demonstrate the effectiveness of the new control structure and its reactivity and robustness when working in dynamic environments

Texte intégralAbstract : Because collaborative robots are aimed at working in the vicinity of human workers without physical security fences, they bring new challenges about security. Even if robots can be conceived to be less harmful, their software has to integrate security features in order to be suitable for dynamic human environments. Since classical path planning algorithms require heavy calculations, it is interesting to modify the trajectory in real time to adapt it to the dangerous environment. In this research project, an inverse kinematics solver, in the form of an optimization problem, is used to generate the command of the robot to follow a trajectory defined offline. The addition of security constraints is studied: first, the manipulability index, which reflects the distance of the robot to singular configurations, is considered. Thus, it should be maximized all along the trajectory to ensure the best mobility available. Then the human is integrated by taking into account its comfort: in order to reduce the stress of working near an unpredictable moving robot, the distance between the end-effector and the human gaze is minimized to guarantee a greater visibility of the task. In both cases, we have presented a new formulation of those criteria to integrate them into the optimization problem. Moreover, the collision avoidance constraint is used, as well as the trajectory relaxation, which allows the robot to deviate from its trajectory for a certain amount of time during the task. Finally tests in simulation and with the real Baxter robot from Rethink Robotics validated our approach and the performance has been evaluated in real conditions, using a RGB-D camera and a real time human tracker software.

Texte intégralIn case of engine failure during aircraft takeoff, there is a speed until which the aircraft can still break to abort the takeoff (Rejected takeoff procedure). Above this speed, the aircraft shall continue the takeoff along the SID trajectory (Standard Instrument Departure) despite the lack of thrust caused by the engine failure. The takeoff parameters must be chosen so that the security of the aircraft is guaranteed in both situations. In mountainous landscape, the obstacle clearance constraints can severely penalise the maximum takeoff weight of the aircraft. In this situation, it is possible to use an alternate trajectory: the EOSID (Engine Out Standard Instrument Departure). The ground track of the EOSID is different from the SID. This trajectory, which is only used in case of engine failure, flies over a relief that is less penalizing. This allows to reduce the regulatory obstacle clearance constraints in engine failure case and to increase the aircraft takeoff weight. The conception of an EOSID is an iterative manual on-ground process that needs several softwares. The aim of this thesis is to formulate and automate this process so as to improve the trajectory quality and to reduce the conception workload. In this aim, the conception process has been analysed and modelled as an optimization problem the objective of which is to maximise the maximum takeoff weight and to minimize the trajectory complexity. A trajectory complexity estimation method has hence been defined and integrated along with the weight within a single criterion. Then the problem is solved with a genetic algorithm that has been developed specifically to handle the trajectory definition format
