This book was released on 2006 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: An absence of guidance on designing complex, dynamic, and networked systems presents challenges to the design of such systems to maximize overall human-machine system performance. An Intelligent Adaptive Interface (IAI) concept and associated technologies have been developed to address this problem. A typical IAI is driven by software agents that can change the display and /or control characteristics to react to the changes of mission and operator states in real time. The work reported here is the result of the two final phases of a three-year project conducted by DRDC Toronto. This project investigated the efficacy of IAIs in a multi-Uninhabited Aerial Vehicle (UAV) scenario. The IAI was modelled as part of the UAV tactical workstations found in a maritime patrol aircraft. In the first phase of the project, a performance model was developed to compare the difference in mission activities with and without IAI agent aids. The simulation results revealed that the control of multiple UAVs is a cognitively complex task with high workload. With the augmentation of automation agents, operators could continue working under high time pressure, resulting in critical tasks being achieved in reduced time. To further test the effectiveness of IAIs and validate the simulation results, a prototype IAI multiagent experimental environment was implemented for an empirical study. Six IAI agent function groups have been integrated into the UAV operator interfaces. Operator's performance was examined with and without IAIs under three different workload conditions. The results from both objective and subjective measures verified the findings of the simulation research. IAIs facilitated a significant reduction in workload and an improvement in situation awareness. This research also developed preliminary guidance on designing IAI systems.

Book excerpt: As ubiquitous as the atmosphere, intelligent adaptive systems (IASs) surround us in our daily lives. When designed well, these systems sense users and their environments so that they can provide support in a manner that is not only responsive to the evolving situation, but unnoticed by the user. A synthesis of recent research and developments on IASs from the human factors (HF) and human–computer interaction (HCI) domains, Intelligent Adaptive Systems: An Interaction-Centered Design Perspective provides integrated design guidance and recommendations for researchers and system developers. The book explores a recognized lack of integration between the HF and HCI research communities, which has led to inconsistencies between the research approaches adopted, and a lack of exploitation of research from one field by the other. The authors integrate theories and methodologies from these domains to provide design recommendations for human–machine developers. They then establish design guidance through the review of conceptual frameworks, analytical methodologies, and design processes for intelligent adaptive systems. The book draws on case studies from the military, medical, and distance learning domains to illustrate intelligent system design to examine lessons learned. Outlining an interaction-centered perspective for designing an IAS, the book details methodologies for understanding human work in complex environments and offers understanding about why and how optimizing human–machine interaction should be central to the design of IASs. The authors present an analytical and design methodology as well as an implementation strategy that helps you choose the proper design framework for your needs.

Book excerpt: This document examines a number of theoretical approaches suitable for creating an intelligent, adaptive interface for control of uninhabited aerial vehicles (UAVs) and uninhabited combat aerial vehicles (UCAVs). These theoretical elements have been combined to produce a comprehensive, cross-disciplinary approach to intelligent system design & implementation, or a generic framework. The framework is generic in that it is designed to be applicable to many other complex military systems with high operator workloads. The proposed framework uses an intelligent software agent-based approach in order to alleviate some of the demands on users performing highly complex tasks in difficult mission scenarios. The document presents overviews of the individual components of the framework and describes the contribution of each along with the rationale for their inclusion in the integrated approach. The generic framework is composed of elements from design approaches including knowledge-based systems, explicit models design, perceptual control theory, and ecological interface design. The final section indicates the recommended sequence for applying the framework.

Available in PDF, EPUB and Kindle. Book excerpt: Early feedback from the operation of uninhabited air vehicles (UAVs) and uninhabited combat air vehicles (UCAVs) indicates the need for improvement in their operator interfaces. This applies for both the effective control of UAVs as well as the management of data and efficient dissemination of the associated information products. One means of addressing this issue is the use of intelligent/adaptive interfaces (IAIs) for decision support. The principal focus of the work reported in this publication was to investigate the efficiency of IAIs in an operational situation. The selected environment involved CP140 aircraft operations in support of counterterrorism activities, and the associated operator interface within which the IAI was modelled was the tactical workstations of a modernized CP140. The operator positions studied were the tactical navigator, UAV operator, and UAV pilot. A one-hour mission scenario was developed and a hierarchical goal analysis & operational sequence diagrams were completed in order to facilitate the development of a performance model. The model was run in two modes: one assuming the operators used a conventional interface and the other assuming interface automation using an IAI. Results are presented showing the difference between mission activities with & without automation as reflected in the time to complete critical task sequences & in other measures of performance.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned Air Vehicles (UAVs) and Unmanned Combat Air Vehicles (UCAVs) are being investigated for use as a new Integrated Intelligence, Surveillance, and Reconnaissance (IISR) platform within the Canadian Forces. At the moment UAV/UCAV control is operator intensive and can involve high levels of workload. In an effort to alleviate those conditions and reduce manning requirements, the current project examined a variety of theoretical approaches to construct a comprehensive, integrated approach to the design and implementation of an intelligent, adaptive, agent-based system for UAV/UCAV control. The resulting generic framework was constructed from the elements of the following design approaches: CommonKADS, MAS-CommonKADS, IDEF Standards, Explicit Models Design, Perceptual Control Theory and Ecological Interface Design. This report provides overviews of each of those approaches and highlights common and complementary elements as part of a recommended generic framework. A sequence for applying the generic framework is provided. The proposed integration of the above techniques into a comprehensive, cross-disciplinary design approach will help serve the goals of reducing operator workloads and manning requirements, while generating a robust, maintainable and reliable system.

Available in PDF, EPUB and Kindle. Book excerpt: The thesis deals with the design and implementation of an Adaptive Flight Control technique for Unmanned Aerial Vehicles (UAVs). The application of UAVs has been increasing exponentially in the last decade both in Military and Civilian fronts. These UAVs fly at very low speeds and Reynolds numbers, have nonlinear coupling, and tend to exhibit time varying characteristics. In addition, due to the variety of missions, they fly in uncertain environments exposing themselves to unpredictable external disturbances. The successful completion of the UAV missions is largely dependent on the accuracy of the control provided by the flight controllers. Thus there is a necessity for accurate and robust flight controllers. These controllers should be able to adapt to the changes in the dynamics due to internal and external changes. From the available literature, it is known that, one of the better suited adaptive controllers is the model based controller. The design and implementation of model based adaptive controller is discussed in the thesis. A critical issue in the design and application of model based control is the online identification of the UAV dynamics from the available sensors using the onboard processing capability. For this, proper instrumentation in terms of sensors and avionics for two platforms developed at UNSW@ADFA is discussed. Using the flight data from the remotely flown platforms, state space identification and fuzzy identification are developed to mimic the UAV dynamics. Real time validations using Hardware in Loop (HIL) simulations show that both the methods are feasible for control. A finer comparison showed that the accuracy of identification using fuzzy systems is better than the state space technique. The flight tests with real time online identification confirmed the feasibility of fuzzy identification for intelligent control. Hence two adaptive controllers based on the fuzzy identification are developed. The first adaptive controller is a hybrid indirect adaptive controller that utilises the model sensitivity in addition to output error for adaptation. The feedback of the model sensitivity function to adapt the parameters of the controller is shown to have beneficial effects, both in terms of convergence and accuracy. HIL simulations applied to the control of roll stabilised pitch autopilot for a typical UAV demonstrate the improvements compared to the direct adaptive controller. Next a novel fuzzy model based inversion controller is presented. The analytical approximate inversion proposed in this thesis does not increase the computational effort. The comparisons of this controller with other controller for a benchmark problem are presented using numerical simulations. The results bring out the superiority of this technique over other techniques. The extension of the analytical inversion based controller for multiple input multiple output problem is presented for the design of roll stabilised pitch autopilot for a UAV. The results of the HIL simulations are discussed for a typical UAV. Finally, flight test results for angle of attack control of one of the UAV platforms at UNSW@ADFA are presented. The flight test results show that the adaptive controller is capable of controlling the UAV suitably in a real environment, demonstrating its robustness characteristics.

Book excerpt: This text is a thorough treatment of the rapidly growing area of aerial manipulation. It details all the design steps required for the modeling and control of unmanned aerial vehicles (UAV) equipped with robotic manipulators. Starting with the physical basics of rigid-body kinematics, the book gives an in-depth presentation of local and global coordinates, together with the representation of orientation and motion in fixed- and moving-coordinate systems. Coverage of the kinematics and dynamics of unmanned aerial vehicles is developed in a succession of popular UAV configurations for multirotor systems. Such an arrangement, supported by frequent examples and end-of-chapter exercises, leads the reader from simple to more complex UAV configurations. Propulsion-system aerodynamics, essential in UAV design, is analyzed through blade-element and momentum theories, analysis which is followed by a description of drag and ground-aerodynamic effects. The central part of the book is dedicated to aerial-manipulator kinematics, dynamics, and control. Based on foundations laid in the opening chapters, this portion of the book is a structured presentation of Newton–Euler dynamic modeling that results in forward and backward equations in both fixed- and moving-coordinate systems. The Lagrange–Euler approach is applied to expand the model further, providing formalisms to model the variable moment of inertia later used to analyze the dynamics of aerial manipulators in contact with the environment. Using knowledge from sensor data, insights are presented into the ways in which linear, robust, and adaptive control techniques can be applied in aerial manipulation so as to tackle the real-world problems faced by scholars and engineers in the design and implementation of aerial robotics systems. The book is completed by path and trajectory planning with vision-based examples for tracking and manipulation.

Download or read book Adaptive Control of Unmanned Aerial Systems written by Zachary Thompson Dydek and published by . This book was released on 2010 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive control is considered to be one of the key enabling technologies for future high-performance, safety-critical systems such as air-breathing hypersonic vehicles. Adaptive flight control systems offer improved performance and increased robustness to uncertainties by virtue of their ability to adjust control parameters as a function of online measurements. Extensive research in the field of adaptive control theory has enabled the design, analysis, and synthesis of stable adaptive systems. We are now entering the stage in which adaptive flight control systems have reached the requisite level of maturity for application to hardware flight platforms. Unmanned aerial systems (UAS) provide a unique opportunity for the transition of adaptive controllers from theory to practice. The small, unmanned aerial vehicles (UAVs) examined in this thesis offer a low-cost, low-risk stepping stone between simulation and application to higher-risk systems in which safety is a critical concern. Unmanned aircraft also offer several benefits over their manned counterparts including extreme persistence, maneuverability, lower weight and smaller size. Furthermore, several missions such as surveillance, exploration, search-and-track, and lifting of heavy loads are best accomplished by a UAS consisting of multiple UAVs. This thesis addresses some of the challenges involved with the application of adaptive flight control systems to UAS. Novel adaptive control architectures are developed to overcome performance limitations of UAS, the most significant of which is a large time delay due to communication and limited onboard processing. Analytical tools that allow the calculation of a theoretically justified time delay limit are also developed. These tools in turn lead to an estimate of the time-delay margin of the closed-loop system which is an essential part of the validation and verification methodology for intelligent flight control systems. These approaches are validated numerically using a series of simulation studies. These controllers and analytical methods are then applied to the UAV, demonstrating improved performance and increased robustness to time delays. Also introduced in this thesis is a novel adaptive methodology for coordinated adaptive control of a multi-vehicle UAS. Including two distinct classes of adaptive algorithms at both the local and global levels was found to result, both in simulation and in actual flight 3 tests, in decreased tracking error for individual vehicles, decreased errors in intervehicle distances, and reduced likelihood of collisions with other vehicles or obstacles in the environment.
