Download or read book Safety And Reliability In Cooperating Unmanned Aerial Systems written by Camille Alain Rabbath and published by World Scientific. This book was released on 2010-01-25 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of recent advances in the analysis and design of health management systems for cooperating unmanned aerial vehicles. Such systems rely upon monitoring and fault adaptation schemes. Motivation for their study comes from the fact that, despite the use of fault-tolerant control software and hardware embedded onboard air vehicles, overall fleet performance may still be degraded after the occurrence of anomalous events such as systems faults and failures. Cooperative health management (CHM) systems seek to provide adaptation to the presence of faults by capitalizing on the availability of interconnected computing, sensing and actuation resources.This monograph complements the proposed CHM concepts by means of case studies and application examples. It presents fundamental principles and results encompassing optimization, systems theory, information theory, dynamics, modeling and simulation. Written by pioneers in cooperative control, health management and fault-tolerant control for unmanned systems, this book is a unique source of information for designers, researchers and practitioners interested in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are critical components of the future naval forces. UAV control and monitoring with autonomous operation will become an absolute necessity and adaptive cooperation of vehicles is the only practical alternative. The objective of this project is to develop and evaluate new methodologies for cooperative (formation) control of multiple unmanned air vehicles. The goal is to have multiple UAVs working together as a group. Instead of separately assigning distinct tasks to each vehicle, the operator would assign tasks to the UAV group, which then determines the best way to accomplish each task, freeing the operator to maintain surveillance over the entire operation. In this project we investigated Path Tracking and obstacle avoidance of UAVs using fuzzy logic method. Algorithms for close formation control of multi-UAVs are developed and simulated. We also investigated fault-tolerant control of single UAVs by neuro-adaptive method. Detailed description of this method is provided in this document. The project has supported S graduate students with 9 technical papers published.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is based on the authors' recent research results on formation control problems, including time-varying formation, communication delays, fault-tolerant formation for multiple UAV systems with highly nonlinear and coupled, parameter uncertainties, and external disturbances. Differentiating from existing works, this book presents a robust optimal formation approach to designing distributed cooperative control laws for a group of UAVs, based on the linear quadratic regulator control method and the robust compensation theory. The proposed control method is composed of two parts: the nominal part to achieve desired tracking performance and the robust compensation part to restrain the influence of highly nonlinear and strongly coupled, parameter uncertainties, and external disturbances on the global closed-loop control system. Furthermore, this book gives proof of their robust properties. The influence of communication delays and actuator fault tolerance can be restrained by the proposed robust formation control protocol, and the formation tracking errors can converge into a neighborhood of the origin bounded by a given constant in a finite time. Moreover, the book provides details about the practical application of the proposed method to design formation control systems for multiple quadrotors and tail-sitters. Additional features include a robust control method that is proposed to address the formation control problem for UAVs and theoretical and experimental research for the cooperative flight of the quadrotor UAV group and the tail-sitter UAV group. Robust Formation Control for Multiple Unmanned Aerial Vehicles is suitable for graduate students, researchers, and engineers in the system and control community, especially those engaged in the areas of robust control, UAV swarming, and multi-agent systems."--

This book was released on 2017 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since several decades ago, unmanned aerial vehicles (UAVs) have attracted a great deal of attention in academic, industrial and military communities. Recently, multiple cooperative UAVs have been applied in various applications such as forest fire detection and fighting, search and exploration, environmental monitoring and surveillance.The main objectives of this dissertation are to design novel algorithms for single quadrotor UAV trajectory tracking control and multiple UAVs for cooperative/formation control. Then, applying these algorithms in forest monitoring and fire detection application, where a group of detection UAVs is required to surround and track the fire perimeter for monitoring and observation mission. Furthermore, a new algorithm for fault-tolerant cooperative control (FTCC) is proposed, in order to mitigate potential UAV fault effect for reliable and safe mission completion. Finally, a fire fighting algorithm is developed for achieving minimum distances for forest fire UAVs to arrive at their assigned fire spots destinations. A combination of sliding mode control (SMC) and linear quadratic regulator (LQR) is used to design a single quadrotor UAV controller, which is then used to design a formation controller of multiple UAVs. Moreover, another formation controller is designed based on SMC to achieve robust formation control against modeling uncertainties and disturbances.Cooperative UAVs are applied in forest monitoring and fire detection application through three stages: search, confirmation and observation. UAVs are assigned to search for potential forest fires in a certain area, once a fire is detected and a fire alarm will be generated by one or more of the UAVs. The UAVs team then reconfigures its formation by following an elliptic fire perimeter, calculated by the ground station (GS) using a fire spread model. Afterward, the fire alarm confirmation stage begins and all UAVs start evenly distributed for surrounding the fire spot according to the UAVs number in the team. When the fire alarm is confirmed, the observation stage starts and UAVs continue tracking the fire along the fire perimeter. SMC is used to design a formation reconfigurable controller to switch between a predefined formation shape during the search stage, to a dynamic surrounding formation. This controller guarantees even distribution of UAVs surrounding the fire spots and the robustness against disturbances. In addition, task assignment is used with multiple fire spots and multiple UAVs teams in order to reduce the mission execution time. Moreover, the proposed control algorithms are implemented to a team of UAVs paired with a team of unmanned ground vehicles (UGVs), by using these UGVs as a take-off and landing platform in forest monitoring and fire detection application.Meanwhile, UAVs may need to leave formation for refueling/recharging during the mission of search, confirmation and observation, or if a fault occurred during the mission due to fire flames, heat or UAV's internal fault sources. Therefore, an FTCC algorithm is designed based on the graph theory to mitigate the fault effect on mission completion, and ensure complete surrounding and data gathering of the fire spots using different fire sensors such as infrared cameras, charge-coupled devices (CCD) cameras and thermal cameras etc.Afterward, data gathered during observation stage are processed in the GS, then dangerous fire spots coordinates are sent to the fire fighting UAVs. The leader UAV, the GS or both can perform the task assignment process using an auction-based or Hungarian algorithms to assign each UAV to a fire spot for deploying fire suppressant. Furthermore, a hybrid approach of control parametrization and time discretization (CPTD) and particle swarm optimization (PSO) is proposed to achieve minimum flight distance for each UAV to arrive at its destination, minimizing fuel/battery consumption. Since PSO cannot solve the continuous control inputs, CPTD is used to provide an approximate piecewise linearization of the control inputs. Thus, PSO can be adopted to achieve the global optimum solution.Finally, the proposed algorithms are being implemented on single and multiple quadrotor UAVs in simulations. While, the leader-follower approach is used in cooperative control in a decentralized manner to avoid the disadvantages of centralization. Thereafter, the proposed algorithms are verified on a set of Qball-X4 quadrotor UAVs and QGV unmanned ground vehicles (UGVs) platforms in real-time experiments through different scenarios.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.
