Book excerpt: The Advanced Navigation Technology (ANT) Center at the Air Force Institute of Technology (AFIT) conducts extensive research in advanced guidance, navigation, and control to exploit the full potential of autonomous Unmanned Aerial Vehicles (UAV). The research in this thesis describes a UAV research platform developed to support the ANT Center?s goals. This platform is now the bedrock for UAV simulation and local flight test at AFIT. The research has three major components. The first component is development of a physical, inertial, and aerodynamic model representing an existing aircraft. A systematic analysis of the airframe leads to a complete geometric, inertial, and aerodynamic representation. The airframe analysis included the use of USAF Digital Datcom, an aerodynamic modeling software tool. Second is the development and implementation of a non-linear, six degree of freedom simulation, employing the developed model. Constructed in Matlab/SIMULINK, the simulation enables control design and pre-flight analysis through out the entire flight envelope. Detailed post-flight analysis was also performed in Matlab/SIMULINK. Additionally, Hardware in the Loop benchmark simulation was constructed and used for initial flight test plans as well as test team training. The third and final component of the research was an experimental flight test program. Both open loop and autonomous flights were conducted. Openloop flights characterized the aircraft dynamics for comparison with the Matlab simulation results. Autonomous flights tuned the autopilot controller through waypoint tracking in preparation for future advanced navigation research and provided data for Hardware in the Loop simulation validation. This report, along with other significant legacy documentation and procedures, builds the foundation from which future AFIT and ANT Center UAV simulations and flight tests are based.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuing development of Unmanned Aerial Vehicles (UAVs) and other low cost aircraft increases the use of the skies for defense, commercial, and recreational use. Aircraft can gain benefits through cooperation. They must also interact to operate safely. Aircraft are being developed for Urban Air Mobility, package delivery, and mapping, among other uses. Flying in a formation has a number of potential benefits. It can allow aircraft to combine sensor information, fly relatively close together taking less room in an airspace, and it can allow for improved fuel efficiency. The primary focus of this research is to coordinate a group of UAVs in a controlled formation, and to allow the aircraft to respond to each other without an external central command center directing their trajectory. The flight formation control system runs a coordination program onboard one of the aircraft, this program creates a virtual leader which all other aircraft in the formation follow. Each aircraft has a preset offset from the leader based on the formation, which provides their target point in the formation. A limited form of flocking, simulating the behavior of a flock of birds, was explored to allow the aircraft to interact directly, ensuring safe spacing around the aircraft. A development platform was also created consisting of a simulation environment and a set of three aircraft. The simulation environment closely models the performance of the aircraft. This allows development in the simulator to be transitioned to the flight testing phase seamlessly. The system was able to function in both the simulation environment and in the real flight testing. It was able to reliably achieve and maintain flight formation. During straight and level flight, only minor errors where observed. During coordinated turns, the observed errors were higher. These observations were consistent in simulation and during flight testing. The results of the flight testing showed that the proposed system is a functional way to coordinate a group of aircraft to fly in formation. The experimentation did show some weaknesses in the implementation of the system, and remediation measures are discussed and proposed for future work.

Download or read book Development of a Nonlinear 6 Degree of Freedom Miniature Rotary Wing Unmanned Aerial Vehicle Software Model and PID Flight Path Controller Using MathWorks Simulink Simulation Environment written by and published by . This book was released on 2009 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the development of a 6-degree of freedom (6-DOF), nonlinear, miniature rotary-wing unmanned aerial vehicle (RW UAV) simulation environment using MathWorks Simulink simulation software. In addition to the modeling process, this research also conducts flight-path controller design using Proportional-Derivative (PD) control techniques. This model's development is motivated by the desire to enable a rapid prototyping platform for design and implementation of various flight control techniques with further seamless transition to the hardware in the loop (HIL) and flight-testing. The T-Rex Align 600 remote controlled helicopter with COTS autopilot was chosen as a prototype rotary UAV platform. The development of the nonlinear simulation model is implemented starting with extensive literature review of helicopter aerodynamics and flight dynamics theory and applying the mathematical models of the helicopter components to generate helicopter inertial frame motion simulations from operator commands. The primary helicopter components modeled in this thesis include the helicopter main rotor inflow, thrust, flapping dynamics, as well as the tail rotor inflow and thrust responses. The inertial frame motions are animated using the Flight Gear Version 0.9.8 software. After obtaining simulations with verifiable results, the nonlinear model is linearized about the hovering flight condition and a linear model is extracted. Lastly, the PD controller is designed and flight path software in the loop (SIL) test results are presented and explained. The SIL tests are conducted for autonomous flight along specified rectangular and figure-8 flight paths.

Download or read book Autonomous Take off and Landing for a Fixed Wing UAV written by Israel Lugo Cárdenas and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work studies some of the most relevant problems in the direction of navigation and control presented in a particular class of mini-aircraft. One of the main objectives is to build a lightweight and easy to deploy vehicle in a short period of time, an unmanned aerial vehicle capable of following a complete mission from take-o⁄ to the following waypoints and complete the mission with an autonomous landing within a delimitated area using a graphical interface in a computer. The Trajectory Generation It is the part that tells the drone where it must travel and are generated by an algorithm built into the drone. The classic result of Dubins is used as a basis for the trajectory generation in 2D and we have extended it to the 3D trajectory generation. A path following strategy developed using the Lyapunov approach is presented to pilot a fixed wing drone across the desired path. The key concept behind the tracking controller is the reduction of the distance between the center of mass of the aircraft p and the point q on the path to zero, as well as the angle between the velocity vector and the vector tangent to the path. In order to test the techniques developed during the thesis a customized C # .Net application was developed called MAV3DSim (Multi-Aerial Vehicle 3D Simulator). The MAV3DSim allows a read / write operation from / to the simulation engine from which we could receive all emulated sensor information and sent to the simulator. The MAV3DSim consists of three main elements, the simulation engine, the computation of the control law and the visualization interface. The simulation engine is in charge of the numeric integration of the dynamic equations of the vehicle, we can choose between a quadrotor and a xed wing drone for use in simulation. The visualization interface resembles a ground station type of application, where all variables of the vehicle s state vector can be represented on the same screen. The experimental platform functions as a test bed for the control law prototyping. The platform consists of a xed wing aircraft with a PX4 which has the autopilot function as well as a Raspberry PI mini-computer which to the implementation of the generation and trajectory tracking. The complete system is capable of performing an autonomous take-o⁄and landing, through waypoints. This is accomplished by using each of the strategies developed during the thesis. We have a strategy for take-o⁄ and landing, which is generated by the navigationon part that is the trajectory generator. Once we have generated the path, it is used by the trajectory tracking strategy and withthat we have landing and take-o⁄ autonomously.

Download or read book Modeling and Control of a Flying Wing Tailsitter Unmanned Aerial Vehicle written by Romain Chiappinelli and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Tailsitters are a special class of fixed-wing unmanned aerial vehicle intended to bridge the gap between rotorcraft and conventional fixed-wing aircraft. These systems are able to perform aerobatic and stationary maneuvers, including vertical takeoff and landing, as well as efficient level flight. However, this flying ability brings a control challenge due to the two distinct flight regimes. During vertical maneuvers, the wings are stalled and only the thrust forces support the aircraft's weight. The rear control surfaces, called elevons, are kept effective due to the slipstream generated by the thrusters. During level flight, the aircraft flies at a substantial forward velocity which generates lift from the wings as well as control authority from the elevons. In this research, a real time simulator is developed for the full flight envelope range, based on a component breakdown method. The simulator includes a flat plate aerodynamics model which includes the effect of control surfaces deflection, a ground contact model, as well as a semi-empirical thruster model. A single quaternion-based controller is developed and implemented in this simulated environment and also tested on the real platform. The autonomous maneuvers needed for a real flight mission are demonstrated through experiments, including vertical takeoff and climb, transition to level flight, back transition, stationary flight, vertical descent and landing. The results from both simulations and flight experiments are compared and used to qualitatively evaluate the performances of the simulator." --
