Book excerpt: This report documents research performed under the contract entitled "A Hardware In-the-Loop Experiment and Simulation Facility for Vision-Based Control of Micro-Air-Vehicles (MAVs)." This experimental facility is comprised of two major components - a wind tunnel facility and a real-time virtual image generation system. Collectively, these two components form a unique closed-loop test for studying vision-based control of autonomous flight vehicles. The most important milestone achieved last year was the design and construction of the new visualization laboratory. This laboratory is equipped to display virtual environments for MAV flight simulations. Currently, a University of Florida campus database, developed by the UF Digital Worlds Institute, is being used as the virtual environment for studying vision-based control of MAVs in urban environments. This report provides a description of the new visualization laboratory and the virtual UF campus database.

This book was released on 2007 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project investigated technologies to enable autonomous flight of agile vehicles in urban environments. Specifically, technologies were developed that related to vision-based feedback for control. The mission profile under consideration was a single vehicle carrying a video camera while flying below the rooftops of a city with no additional sensors or pre-existing map information. As such, substantial progress was made in the areas of feature-point tracking, state estimation, scene reconstruction, robustness to camera calibration, daisy-chaining navigation, mapping, path planning, and feedback characterization. An integrated approach was used that (be used on multi-disciplinary analysis for decision making and control commands. The project spiraled the maturation of technologies from theory to simulation to flight testing. The simulation relied upon a hardware-in-the-loop simulation facility that allowed the physical camera to record measurements from high-fidelity graphics and thus consider the effects of distortion and nonlinearities.

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This thesis presents the design, fabrication, capabilities, and analysis of a test-bed Micro Air Vehicle (MAV) used in developing a vision-based flight control algorithm. Vision-based controlled flight and its further developments are geared towards use on MAVs of the future. A test-bed airplane was designed from MAV concepts, and was large enough to accommodate the current commercial components available on the market. Two generations of the vision-based MAV were developed and tested. Each generation had 0.6 m wingspan and used a pusher configuration with a flexible wing concept. The second generation, however, had an improved fuselage and wing design, drive system, and a unique morphing mechanism. Both vehicles were tested and compared during numerous flight and wind tunnel tests. Effects of the morphing mechanism on the flexible wing were analyzed in the wind tunnel using the digital image correlation method.

Book excerpt: This effort helped to solidify the linkage between the aerodynamic and guidance and control aspects of micro air vehicles. Micro air vehicles are characterized by small vehicle size (O 10 centimeters), low flight speeds (O 10 meters per second), and low Reynolds number (O 10,000 - 100,000). These micro air vehicles (MAVs) are unique in the fact that they are inherently multi-functional systems. That is, sub-systems within the MAV perform more than one task. In this regard, aerodynamic and guidance and control aspects of the MAVs need to be developed in concert. New methods for guidance and control, such as vision-based and biometrically-inspired methods, will rely on detailed understanding of the MAV aerodynamic characteristics to be effective. This effort focused on the influence of flexible airframes to provide for a much more robust airframe for micro-class air vehicles. Results demonstrated that airframes with inherent flexibility are more tolerant to disturbances (i.e., gusts) and are better suited to relevant Air Force Missions. Future work will focus on the tuning of the vehicle structure and sensing of vehicle deformations to provide enhanced control.

Book excerpt: These annotated Final Review charts summarize the work performed for the Open Control Platform (OCP) Software Enabled Control (SEC) Hardware in the Loop (HITL) Delivery Order #0008 under the Air Vehicles Technology Integration Program (AVTIP) contract awarded to Northrop Grumman Corporation (NGC). The OCP HITL program developed a Hardware-in-the Loop facility for demonstrating and evaluating High-Confidence Software and Systems (HCSS). Boeing, AFRL, and NGC created and implemented an architecture that provided AFRL/VAC with the baseline capability to test control algorithms (including collision avoidance and Fault Detection Isolation), run combined piloted and autonomous vehicle simulations, and created an interface to AFRL visualization software Virtual Battlefield Management System (VBMS) and SubrScene.

Available in PDF, EPUB and Kindle. Book excerpt: Air Force Research Laboratory (AFRL) researchers at the Aerospace Vehicle Technology Assessment and Simulation (AVTAS) Laboratory are currently conducting the Open Control Platform (OCP) Hardware-In-The-Loop (HITL) project sponsored by the DARPA Software Enabled Control (SEC) Program. The purpose of this project is to develop the capability to be an OCP test-bed and to evaluate the OCP controls and simulation environment for a specific test case. The OCP provides an open, middleware-enabled software framework and development platform for developers of distributed and embedded software applications. The middleware isolates the programmer from the details of the operating system and provides a mechanism for communication with other OCP software components. A Traffic Collision Avoidance System (TCAS) was chosen as a representative flight controls application to exercise OCP. The programmatic approach taken by the OCP-HITL project is a series of simulation experiments with increasing complexity.

Download or read book A Closed Loop Research Platform that Enables Dynamic Control of Wing Gait Patterns in a Vertically Constrained Flapping Wing - Micro Air Vehicle written by Hermanus Van Niekerk Botha and published by . This book was released on 2016 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in Flapping Wing - Micro Air Vehicles(FW-MAVs) has been growing in recent years. Work ranging from mechanical designs to adaptive control algorithms are being developed in pursuit of mimicking natural flight. FW-MAV technology can be applied in a variety of use cases such a military application and surveillance, studying natural ecological systems, and hobbyist commercialization. Recent work has produced small scale FW-MAVs that are capable of hovering and maneuvering. Researchers control maneuvering in various ways, some of which involve making small adjustments to the core wing motion patterns (wing gaits) which determine how the wings flap. Adaptive control algorithms can be implemented to dynamically change these wing motion patterns to allow one to use gait based modification controllers even after damage to a vehicle or its wings occur. This thesis will create and present a hardware research platform that enables hardware-in-the-loop experimentation with core wing gait adaptation methods.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Micro Air Vehicles (MAVs) are becoming vastly popular in the areas of surveillance and reconnaissance for military and civilian use; however, their instability due to their small size renders them useful to only a handful of pilots. We propose implementing a GPS-based navigation system for use in autonomous flight of micro air vehicles. Previous efforts in this area have produced a vision-based horizon tracking algorithm capable of sustained level flight with user input. Our goal is to improve on this flight system using information from a GPS receiver. In this thesis we first introduce the current vision-based navigation system and discuss its limitations. We next discuss the proposed improvements to the navigation system through GPS. Then, we describe the design of the hardware system and software algorithms for navigation and control. The GPS- and vision-based navigation system has been successfully integrated and tested in multiple ground-based simulations at the University of Florida.
