Optimal Control Of Fully Routed Air Traffic In The Presence Of Uncertainty And Kinodynamic Constraints, Christopher D. Arendt 2014 Air Force Institute of Technology

Optimal Control Of Fully Routed Air Traffic In The Presence Of Uncertainty And Kinodynamic Constraints, Christopher D. Arendt

Theses and Dissertations

A method is presented to extend current graph-based Air Traffic Management optimization frameworks. In general, Air Traffic Management is the process of guiding a finite set of aircraft, each along its pre-determined path within some local airspace, subject to various physical, policy, procedural and operational restrictions. This research addresses several limitations of current graph-based Air Traffic Management optimization methods by incorporating techniques to account for stochastic effects, physical inertia and variable arrival sequencing. In addition, this research provides insight into the performance of multiple methods for approximating non-differentiable air traffic constraints, and incorporates these methods into a generalized weighted-sum representation ...

A Decision Making Framework With Modflow-Fmp2 Via Optimization: Determining Trade-Offs In Crop Selection, K R. Fowler, E W. Jenkins, C Ostrove, J C. Chispell, M W. Farthing, M Parno

US Army Corps of Engineers

Farmers in regions experiencing water stress or drought conditions can struggle to balance their crop portfolios. Periods of low precipitation often lead to increased, unsustainable reliance on groundwatersupplied irrigation. As a result, regional water management agencies place limits on the amount of water which can be obtained from groundwater, requiring farmers to reduce acreage for more water-intensive crops or remove them from the portfolio entirely. Real-time decisions must be made by the farmer to ensure viability of their farming operation and reduce the impacts associated with limited water resources. Evolutionary algorithms, coupled with accurate, flexible, realistic simulation tools, are ideal ...

Cooperative Planning For Uas-Based Sensor Networks In Realistic Communication Environments, Maciej Stachura 2014 University of Colorado Boulder

Cooperative Planning For Uas-Based Sensor Networks In Realistic Communication Environments, Maciej Stachura

Aerospace Engineering Sciences Graduate Theses & Dissertations

This dissertation develops a unified, tractable algorithm for distributed planning for multiple unmanned aircraft based sensor networks with performance bounds. An information-theoretic objective function is derived that incorporates sensing and communication to guide a cooperative team of unmanned aircraft. The communication is modelled with packet erasure channels for each link in a multi-hop mesh network. This objective is shown to be intractable and assumptions are made to find a tractable formulation. This tractable formulation is then distributed using the chain rule of mutual information and optimization algorithms are designed with performance bounds for different scenarios and compared against the fully ...


Temporal-Logic Based Runtime Observer Pairs For System Health Management Of Real-Time Systems, Thomas Reinbacher, Kristin Yvonne Rozier, Johann Schumann 2013 Vienna University of Technology

Temporal-Logic Based Runtime Observer Pairs For System Health Management Of Real-Time Systems, Thomas Reinbacher, Kristin Yvonne Rozier, Johann Schumann

Kristin Yvonne Rozier

We propose a real-time, Realizable, Responsive, Unobtrusive Unit (rt-R2U2) to meet the emerging needs for System Health Management (SHM) of new safety-critical embedded systems like automated vehicles, Unmanned Aerial Systems (UAS), or small satellites. SHM for these systems must be able to handle unexpected situations and adapt specifications quickly during flight testing between closely-timed consecutive missions, not mid-mission, necessitating fast reconfiguration. They must enable more advanced probabilistic reasoning for diagnostics and prognostics while running aboard limited hardware without affecting the certified on-board software. We define and prove correct translations of two real-time projections of Linear Temporal Logic to two types ...


Runtime Observer Pairs And Bayesian Network Reasoners On-Board Fpgas: Flight-Certifiable System Health Management For Embedded Systems, Johannes Geist, Kristin Y. Rozier, Johann Schumann 2013 Research Institute for Advanced Computer Science (RIAC)

Runtime Observer Pairs And Bayesian Network Reasoners On-Board Fpgas: Flight-Certifiable System Health Management For Embedded Systems, Johannes Geist, Kristin Y. Rozier, Johann Schumann

Kristin Yvonne Rozier

Safety-critical systems, like Unmanned Aerial Systems (UAS) that must operate totally autonomously, e.g., to support ground-based emergency services, must also provide assurance they will not endanger human life or property in the air or on the ground. Previously, a theoretical construction for paired synchronous and asynchronous runtime observers with Bayesian reasoning was introduced that demonstrated the ability to handle runtime assurance within the strict operational constraints to which the system must adhere. In this paper, we show how to instantiate and implement temporal logic runtime observers and Bayesian network diagnostic reasoners that use the observers’ outputs, on-board a field-standard ...


Interaction Model Of Functions In The National Airspace System, Nathan F. Koerschner, Steven J. Landry 2013 Purdue University

Interaction Model Of Functions In The National Airspace System, Nathan F. Koerschner, Steven J. Landry

The Summer Undergraduate Research Fellowship (SURF) Symposium

The National Airspace System (NAS) is comprehensively described by five functions derived from big-picture goals: (1) conflict detection and resolution, (2) controlling aircraft states, (3) traffic flow management, (4) controlling passenger states, and (5) controlling company resources. It can be reasonably assumed that these functions interact in some way; this interaction is currently unknown. A model of the entire NAS would be helpful in discovering these interactions, yet no such comprehensive model exists. To address this problem an agent-based state-based model was created in MATLAB. To date, only functions (1) and (2) were implemented. Running the model shows that there ...

Industrial and Manufacturing Systems Engineering Patents

Integrated surveillance systems and methods for processing multiple sensor inputs and determining a best route for avoiding multiple hazards. An example method performed on a first aircraft includes generating a plurality of routes for avoiding a previously determined alert from a first advisory system. Then, probability of success information is generated at other advisory systems for each of the plurality of routes. The best route of the plurality of routes is determined based on the generated probabilities and output to the flight crew or other aircraft. The probability of success information includes a previously defined uncertainty value. The uncertainty value ...


The Multi-Tier Mission Architecture And A Different Approach To Entry, Descent And Landing, Jeremy Straub 2013 SelectedWorks

The Multi-Tier Mission Architecture And A Different Approach To Entry, Descent And Landing, Jeremy Straub

Jeremy Straub

Planetary missions are generally very well planned out. Where the spacecraft will be deployed, what it will do there and in what order are generally determined before launch. While some allowance is made for greater depth exploration of scientifically interesting items identified during the investigation, a successful mission is (generally) one that doesn’t deviate significantly from its planning. When sending an initial mission to an unsurveyed planet or moon, however, this approach is not suitable. Current space technology provides the capability to send a combined survey and lander mission (instead of conducting an initial survey mission and following it ...


Enabling Interplanetary Small Spacecraft Science Missions With Model Based Data Analysis, Jeremy Straub 2013 SelectedWorks

Enabling Interplanetary Small Spacecraft Science Missions With Model Based Data Analysis, Jeremy Straub

Jeremy Straub

Small spacecraft operating outside of Earth orbit are significantly constrained by the communica- tions link available to them. This is particularly true for stand-alone craft that must rely on their own antenna and transmission systems (for which gain and available power generation are limited by form factor); it is also applicable to ‘hitchhiker’-style missions which may be able to utilize (quite likely very limited amounts of) time on the primary spacecraft’s communications equip- ment for long-haul transmission.

This poster presents the adaptation of the Model-Based Transmission Reduction (MBTR) frame- work’s Model-Based Data Analysis (MBDA) component for use ...

Uav Formation Flight Utilizing A Low Cost, Open Source Configuration, Christian W. Lopez

Master's Theses and Project Reports

The control of multiple unmanned aerial vehicles (UAVs) in a swarm or cooperative team scenario has been a topic of great interest for well over a decade, growing steadily with the advancements in UAV technologies. In the academic community, a majority of the studies conducted rely on simulation to test developed control strategies, with only a few institutions known to have nurtured the infrastructure required to propel multiple UAV control studies beyond simulation and into experimental testing. With the Cal Poly UAV FLOC Project, such an infrastructure was created, paving the way for future experimentation with multiple UAV control systems ...


Desktop Warfare: Robotic Collaboration For Persistent Surveillance, Situational Awareness And Combat Operations, Jeremy Straub 2013 SelectedWorks

Desktop Warfare: Robotic Collaboration For Persistent Surveillance, Situational Awareness And Combat Operations, Jeremy Straub

Jeremy Straub

Robotic sensing and weapons platforms can be controlled from a desktop workstation on the other side of the planet from where combat is occurring. This minimizes the potential for injury to soldiers and increases operational productivity. Significant work has been undertaken and is ongoing related to the autonomous control of battlefield sensing and warfighting systems. While many aspects of these operations can be performed autonomously, in some cases it is necessary (due to technical limitations) or desirable (due to legal or political implications) to involve humans in the low-level decision making. This paper reviews a number of specific applications where ...


Effects Of Stereoscopic 3d Digital Radar Displays On Air Traffic Controller Performance, Jason G. Russi 2013 Air Force Institute of Technology

Effects Of Stereoscopic 3d Digital Radar Displays On Air Traffic Controller Performance, Jason G. Russi

Theses and Dissertations

Air traffic controllers are responsible for directing air traffic based upon decisions made from traffic activity depicted on 2Dimensional (2D) radar displays. Controllers must identify aircraft and detect potential conflicts while simultaneously developing and executing plans of action to ensure safe separation is maintained. With a nearly 100% increase in traffic expected within the next decade (FAA, 2012a), controllers' abilities to rapidly interpret spacing and maintain awareness for longer durations with increased workload will become increasingly imperative to safety. The current display design spatially depicts an aircraft's position relative to the controller's airspace as well as speed, altitude ...

Pseudolite Architecture And Performance Analysis For The Faa's Nextgen Airspace, Joseph A . Czabaranek

Theses and Dissertations

By 2025 the FAA plans to have fully implemented its NextGen Airspace design. NextGen takes advantage of modern positioning technologies as well as automation, data sharing, and display technologies that will allow more efficient use of our ever busier National Airspace (NAS). A key element of NextGen is the transition from surveillance RADAR providing aircraft separation and navigation to the use of the GPS and Automatic Dependent Surveillance Broadcast (ADS-B). ADS-B couples the precision of the GPS with networked ground and airborne receivers to provide precise situational awareness to pilots and controllers. The result is increased safety, capacity, and access ...


A Human Proximity Operations System Test Case Validation Approach, Justin Huber, Jeremy Straub 2013 SelectedWorks

A Human Proximity Operations System Test Case Validation Approach, Justin Huber, Jeremy Straub

Jeremy Straub

A Human Proximity Operations System (HPOS) poses numerous risks in a real world environment. These risks range from mundane tasks such as avoiding walls and fixed obstacles to the critical need to keep people and processes safe in the context of the HPOS’s situation-specific decision making. Validating the performance of an HPOS, which must operate in a real-world environment, is an ill posed problem due to the complexity that is introduced by erratic (non-computer) actors. In order to prove the HPOS’s usefulness, test cases must be generated to simulate possible actions of these actors, so the HPOS can ...
