Design Of An All-In-One Embedded Flight Control System, Joel D. Elmore
Theses and Dissertations
This thesis describes an all-in-one flight control system (FCS) that was designed for unmanned aerial vehicles (UAVs). The project focuses on the embedded hardware aspect of a stand-alone system with low-cost and reliability in mind.
Development Of Mobile Ad-Hoc Network For Collaborative Unmanned Aerial Vehicles, Siva Teja Patibandla
Development Of Mobile Ad-Hoc Network For Collaborative Unmanned Aerial Vehicles, Siva Teja Patibandla
Theses and Dissertations
The purpose of this research was to develop a mobile ad-hoc network for collaborative Unmanned Aerial Vehicles (UAVs) based on a mesh networking standard called IEEE 802.11s. A low-cost, small form-factor, IEEE 802.11a based wireless modem was selected and integrated with the existing flight control system developed at Virginia Commonwealth University (VCU) UAV Laboratory. A self-configurable user-space application on the wireless modem was developed to provide functionality to collaborative algorithms, and to monitor the performance of the wireless network. The RAMS simulator, developed at VCU, was upgraded to support the simulation of advanced networking capabilities by integrating with a simulator …
Development Of A Multiple Vehicle Collaborative Unmanned Aerial System, Lloyd B. Mize Iv
Development Of A Multiple Vehicle Collaborative Unmanned Aerial System, Lloyd B. Mize Iv
Theses and Dissertations
The purpose of this research was to design a multiple UAV system with collaborative operation. This project is built on work that has been done in the field of Unmanned Systems at VCU and is aimed at providing a starting point for research into collaborative control of multiple UAVs. The current GCS software was extended to include multiple vehicles per single controller via a new communication protocol. Many changes were made to the user interface to facilitate controlling multiple vehicles with a single operator. A second processor, called an MCS, was added to each vehicle to allow for greater flexibility …
Development Of A Flexible Fpga-Based Platform For Flight Control System Research, Robert Demott
Development Of A Flexible Fpga-Based Platform For Flight Control System Research, Robert Demott
Theses and Dissertations
This work is part of ongoing research conducted at Virginia Commonwealth University relating to unmanned aerial vehicles. The primary objective of this thesis was to develop a flexible, high-performance autopilot platform in order to facilitate research on advanced flight control algorithms. A dual FPGA-based system architecture utilizing a stacked, multi-board design was created to meet this goal. Processing tasks were split between the two FPGA devices, allowing for improved system timing and increased throughput. A combination of analog and digital filtering techniques were employed in the new system, resulting in enhanced sensor accuracy and precision compared to the previous generation …
Development Of A Low Cost Autopilot System For Unmanned Aerial Vehicles, Jose Ortiz
Development Of A Low Cost Autopilot System For Unmanned Aerial Vehicles, Jose Ortiz
Theses and Dissertations
The purpose of this thesis was to develop a low cost autonomous flight control system for small unmanned aerial vehicles with the aim to support collaborative systems. A low cost hardware solution was achieved by careful selection of sensors, integration of hardware subsystems, and the use of new microcontroller technologies. Flight control algorithms to guide a vehicle though waypoint based flight paths and loiter about a point were implemented using direction fields. A hardware in the loop simulator was developed to ensure proper operation of all hardware and software components prior to flight testing. The resulting flight control system achieved …
