Book excerpt: Unmanned Areal Vehicles (UAVs) can provide significant contributions to information gathering in military missions. UAVs can be used to capture both full motion video and still imagery of specific target locations within the area of interest. In order to improve the effectiveness of a reconnaissance mission, it is important to visit the largest number of interesting target locations possible, taking into consideration operational constraints related to fuel usage between target locations, weather conditions and endurance of the UAV. We model this planning problem as the well-known orienteering problem, which is a generalization of the traveling salesman problem. Given the uncertainty in the military operational environment, robust planning solutions are required. As such, our model takes into account uncertainty in the fuel usage between targets (for instance due to weather conditions) as well as uncertainty in the importance of visiting specific target locations. We report results using different uncertainty sets that specify the degree of uncertainty against which any feasible solution will be protected. We also compare the probability that a solution is feasible for the robust solution on one hand and the solution found with average fuel usage and expected value of information on the other. In doing so, we show how the sustainability of a UAV mission can be significantly improved.

Download or read book Robust Trajectory Planning for Unmanned Aerial Vehicles in Uncertain Environments written by Brandon Douglas Luders and published by . This book was released on 2008 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: As unmanned aerial vehicles (UAVs) take on more prominent roles in aerial missions, it becomes necessary to increase the level of autonomy available to them within the mission planner. In order to complete realistic mission scenarios, the UAV must be capable of operating within a complex environment, which may include obstacles and other no-fly zones. Additionally, the UAV must be able to overcome environmental uncertainties such as modeling errors, external disturbances, and an incomplete situational awareness. By utilizing planners which can autonomously navigate within such environments, the cost-effectiveness of UAV missions can be dramatically improved.This thesis develops a UAV trajectory planner to efficiently identify and execute trajectories which are robust to a complex, uncertain environment. This planner, named Efficient RSBK, integrates previous mixed-integer linear programming (MILP) path planning algorithms with several implementation innovations to achieve provably robust on-line trajectory optimization. Using the proposed innovations, the planner is able to design intelligent long-term plans using a minimal number of decision variables. The effectiveness of this planner is demonstrated with both simulation results and flight experiments on a quadrotor testbed.Two major components of the Efficient RSBK framework are the robust model predictive control (RMPC) scheme and the low-level planner. This thesis develops a generalized framework to investigate RMPC affine feedback policies on the disturbance, identify relative strengths and weaknesses, and assess suitability for the UAV trajectory planning problem. A simple example demonstrates that even with a conventional problem setup, the closed-loop performance may not always improve with additional decision variables, despite the resulting increase in computational complexity. A compatible low-level troller is also introduced which significantly improves trajectory-following accuracy, as demonstrated by additional flight experiments.

Download or read book Robust Multi unmanned Aerial Vehicles Planning in Dynamic and Uncertain Environments written by Chung Tin and published by . This book was released on 2004 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Future unmanned aerial vehicles (UAVs) are expected to operate with higher level of autonomy to execute very complex military and civilian applications. New methods in planning and execution are required to coordinate these vehicles in real-time to ensure maximal efficiency of the team activities. These algorithms must be fast to enable rapid replanning in a dynamic environment. The planner must also be robust to uncertainty in the situational awareness. This thesis investigates the impact of information uncertainty and environmental changes to the task assignment and path planning algorithms. Several new techniques are presented that both speed up and embed robustness into previously published algorithms. The first is an incremental algorithm that significantly reduces the time required to update the cost map used in the task assignment when small changes occur in a complex environment. The second introduces a new robust shortest path algorithm that accounts for uncertainty in the arc costs. The algorithm is computational tractable and is shown to yield performance and robustness that are comparable to more sophisticated algorithms that are not suitable for real-time implementation. Experimental results are presented using this technique on a rover testbed. This thesis also extends a UAV search algorithm to include moving targets in the environment. This new algorithm coordinates a team of UAVs to search an unknown environment while balancing the need to track moving targets. These three improvements have had a big impact because they modify the Receding Horizon Mixed-Integer Linear Programming (RH-MILP) control hierarchy to handle uncertainty and properly react to rapid changes in the environment. Hence, these improvements enable the RH-MILP controller to be implemented in more realistic scenarios.

This book was released on 2013-03-09 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with decision making in environments of significant data un certainty, with particular emphasis on operations and production management applications. For such environments, we suggest the use of the robustness ap proach to decision making, which assumes inadequate knowledge of the decision maker about the random state of nature and develops a decision that hedges against the worst contingency that may arise. The main motivating factors for a decision maker to use the robustness approach are: • It does not ignore uncertainty and takes a proactive step in response to the fact that forecasted values of uncertain parameters will not occur in most environments; • It applies to decisions of unique, non-repetitive nature, which are common in many fast and dynamically changing environments; • It accounts for the risk averse nature of decision makers; and • It recognizes that even though decision environments are fraught with data uncertainties, decisions are evaluated ex post with the realized data. For all of the above reasons, robust decisions are dear to the heart of opera tional decision makers. This book takes a giant first step in presenting decision support tools and solution methods for generating robust decisions in a variety of interesting application environments. Robust Discrete Optimization is a comprehensive mathematical programming framework for robust decision making.

This book was released on 2010-11-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: An invaluable addition to the literature on UAV guidance and cooperative control, Cooperative Path Planning of Unmanned Aerial Vehicles is a dedicated, practical guide to computational path planning for UAVs. One of the key issues facing future development of UAVs is path planning: it is vital that swarm UAVs/ MAVs can cooperate together in a coordinated manner, obeying a pre-planned course but able to react to their environment by communicating and cooperating. An optimized path is necessary in order to ensure a UAV completes its mission efficiently, safely, and successfully. Focussing on the path planning of multiple UAVs for simultaneous arrival on target, Cooperative Path Planning of Unmanned Aerial Vehicles also offers coverage of path planners that are applicable to land, sea, or space-borne vehicles. Cooperative Path Planning of Unmanned Aerial Vehicles is authored by leading researchers from Cranfield University and provides an authoritative resource for researchers, academics and engineers working in the area of cooperative systems, cooperative control and optimization particularly in the aerospace industry.

Available in PDF, EPUB and Kindle. Book excerpt: Lessons from recent combat experiences in Kosovo, Afghanistan and Iraq have shown that UAVs can provide vastly improved acquisition and more rapid dissemination of Intelligence, Surveillance and Reconnaissance (ISR) data. They are one of the principal contributors to successful outcomes for the United States, in these campaigns. The benefits and promise offered by UAVs in surveillance, targeting and attack have captured the attention of senior military and civilian officials in the Defense Department (DoD), members of Congress, and the public alike. Indeed, these recent combat operations appear to indicate that unmanned air systems have at last come of age. There is no longer any question of the technical viability and operational utility of UAVs. The success of UAVs in recent conflicts represents a historic opportunity to exploit the transformational capabilities inherent in UAVs/Uninhabited Combat Aerial Vehicles (UCAVs). Transformation is not a term, it is a philosophy. Transformation is a predisposition to exploring adaptations of existing and new systems, doctrine and organizations. True transformation is not the result of a one-time improvement, but of sustained and determined effort. For example, the American forces used multiple Predator UAVs during Operation Iraqi Freedom (OIF) to provide a far more comprehensive operational perspective across the theater to the Combined Air Operations Center by integrating the Predator common operating picture with the Falcon View mission planning system. There is now another mission imperative and that is distance. During this review the new concept of Global Persistence Surveillance has specifically focused on the contributions of UAVs and UCAVs. During OIF Predator UAVs also enabled time-critical targeting via streaming video to strike platforms. Likewise one Global Hawk in the Iraqi theater from 8 March 03 to 23 April 03 accounted for 55% of the Time Sensitive Targets generated to kill air defense equipment. In 16 missions, Global Hawk located 13 Surface-to-Air Missile (SAM) batteries, 50 SAM launchers, over 70 SAM transport vehicles and over 300 tanks. Notwithstanding the success of UAVs in OIF, UAVs have not been fully "embedded" in current Concepts of Operations (CONOPS) or valued with effects driven methodology. Future UAV programs must be conceived with this mix in mind, i.e. predefined operational concepts and effects driven methodology. UAVs are ideal systems to support the emerging joint character and the asymmetric nature of warfare. The Task Force feels it is time for DoD and the Services to move forward and make UAVs and UCAVs an integral part of the force structure, not an "additional asset." To do so requires appropriate planning, appropriate budgeting, and continued management attention of DoD and Service leadership. The DoD and the Services have already started to integrate UAVs into their force structure plans. Currently there are UAV plans and roadmaps within the DoD and Services and the FY 04 budget also shows substantial increases in funding of UAV programs. While progress has been made in planning and funding for UAVs, the Services need to move from deconfliction to integration to interdependence. UAV capabilities should be assessed in the larger context of the Global Persistent Surveillance. UAVs can ideally complement current architectures for Future Imagery Architecture, New Imagery System, and Space Based Radar. This study identifies steps the Department of Defense and Armed Services can take to field a robust UAV and UCAV capability. The recommendations in his executive summary indicate the Task Force's top level recommendations. Additional recommendations can be found in the body of the report. The Task Force's findings and recommendations fall into eight subject areas and are described in this executive summary in order of importance.

This book was released on 2014-01-10 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the emerging field of planning and decision making for aerial robots. An aerial robot is the ultimate form of Unmanned Aerial Vehicle, an aircraft endowed with built-in intelligence, requiring no direct human control and able to perform a specific task. It must be able to fly within a partially structured environment, to react and adapt to changing environmental conditions and to accommodate for the uncertainty that exists in the physical world. An aerial robot can be termed as a physical agent that exists and flies in the real 3D world, can sense its environment and act on it to achieve specific goals. So throughout this book, an aerial robot will also be termed as an agent. Fundamental problems in aerial robotics include the tasks of spatial motion, spatial sensing and spatial reasoning. Reasoning in complex environments represents a difficult problem. The issues specific to spatial reasoning are planning and decision making. Planning deals with the trajectory algorithmic development based on the available information, while decision making determines priorities and evaluates potential environmental uncertainties. The issues specific to planning and decision making for aerial robots in their environment are examined in this book and categorized as follows: motion planning, deterministic decision making, decision making under uncertainty and finally multi-robot planning. A variety of techniques are presented in this book, and a number of relevant case studies are examined. The topics considered in this book are multidisciplinary in nature and lie at the intersection of Robotics, Control Theory, Operational Research and Artificial Intelligence.
