This book was released on 1998 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modern engineer has a myriad of new tools to assist in the design and implementation of ever increasingly complex control systems. A promising emerging technology is rapid prototyping. By totally integrating the development process, a Rapid Prototyping System (RPS) takes the designer from initial concept to testing on actual hardware in a systematic, logical sequence. At the Naval Postgraduate School (NPS), we have applied the concept of rapid prototyping to the discipline of flight control. The NPS RPS consists of a commercially available rapid prototyping software suite and open architecture hardware to permit the greatest possible range of control and navigation projects. The RPS is crucial in that it allows students to participate in projects from the initial concept to the flight testing phase of the design process. This thesis will describe in detail two of these projects; the development of an Airspeed Controller using the RPS tools; and the integration of a Voice Control System developed by ViA, Inc. of Northfield, Minnesota. Both projects demonstrate the inherent flexibility and risk reduction of the rapid prototyping a roach to system design.

This book was released on 2001-09-01 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of unmanned aerial vehicles (UAVs) to current and future military operations cannot be understated. This rapidly developing field requires the ability to quickly develop and evaluate advanced control concepts. The FROG UAV serves as a test bed for advanced control and sensor projects at the Naval Postgraduate School. Previous control system projects have made use of a low performance electromechanical autopilot onboard the UAV. This autopilot imposed significant limitations on the responsiveness of the FROG. This project developed and tested an off board digital flight control system for use in lieu of the previous electromechanical device. The digital flight controller was developed using the Matrixx rapid prototyping system and a previously validated dynamic model of the FROG. Surrogate flight control servo actuators were characterized in the laboratory and added to the plant model. Classic inner/ outer loop controllers were developed for yaw damping and speed, altitude and heading control. The system was then successfully demonstrated%ted with hardware in the loop in the lab. The FROG was then instrumented and a command uplink latency of 170 MS was discovered. This introduced excessive phase lag into the system, which drove the flight controllers unstable. An alternate serial uplink method was developed and tested which reduced the command latency to 76 MS however the remaining phase lag resulted in limit cycle oscillation. Laboratory tests indicated that the current flight controller could withstand a maximum of 50 MS command path delay; without modification.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned Aerial Vehicles (UAVs) popularity has increased substantially in the last few years. UAVs capabilities continue to improve as a result of advances in battery technology, communication, navigation systems and electronics. Increased popularity has driven researchers to improve UAVs reliability and safety which is reflected by the number of publications and accelerating educational programs interest. UAVs are suited for a wide range of civilian and military applications; however, UAVs currently can not integrate with civilian airspace because of stringent safety requirements. Hence, it is necessary to push the envelope for UAVs design and control so that they can learn from nature and have more self-aware capabilities to improve safety and reliability. This dissertation addresses some challenges involved with flight controller learning based on real-time modeling of UAV. Plenty of UAV applications require different operational capabilities within a composite mission. These capabilities include landing and taking off using short runways, while being able to perform missions that require a high cruise speed i.e. tracking applications. A composite mission also requires the aircraft to be able to hover or operate with low cruise speeds for applications involving stationary moments. All of these different operational modes require a hybrid aircraft design that combines fixed wing aircraft capabilities and Vertical Take-Off and Landing (VTOL) aircraft capabilities. However, extensive resources required for hybrid aircraft design prohibited the discovery of different revolutionary designs. The work presented in this dissertation describes the development of a rapid modeling, prototyping and controller design platform of an unmanned quadrotor aircraft. Three main objectives are investigated: intelligent excitation input design, real-time parameter estimation, and learning control. Real-time estimation of dynamic model parameters is important for control adaptation. However, the aircraft model estimation performance can be severely degraded by an active control system and highly collinear model terms such as those found on a quadrotor unmanned aircraft. Recursive Fourier Transform Regression was applied to estimate parameters of different model forms/structures and using different excitation levels. The generated models are utilized to reconfigure a Nonlinear Dynamic Inversion (NDI) controller considering different testing conditions: normal, failure, and learning flights. Finally,an intelligent input design technique is proposed which enables autonomous identification of the vehicle’s response modal frequencies and emphasizes excitation power accordingly.

This book was released on 1996-09-01 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of control systems has witnessed an explosion in state- space techniques addressing a variety of critical design issues facing control engineers today. Modem computational tools, such as the MATRIX(x) Product Family developed by Integrated Systems Incorporated, allow the designer o quickly design, test and implement control systems based on these state-space techniques. These new computing advances shorten the time required to complete a control design from a few years to a few months. However, as the design process progressed new inputs and outputs were required, which usually resulted in a confusing mess of connections that were hard to follow. Therefore, a universal system was needed that could be used on any controller design to aid in the understanding and tracking of the controller's inputs and outputs. A description of this system is given along with a detailed step by step process on how it was implemented on a Unmanned Air Vehicle (UAV).

This book was released on 1998-12-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this thesis is to design, integrate and flight test a Flight Management System (FMS) for the computer control of an unmanned air vehicle (UAV). By combining modern control design techniques and the capabilities of a Rapid Prototyping System (RPS), we were able to safely go from concept to flight test in a relatively short amount of time without sacrificing thoroughness in computer simulation, code validation and verification, or hardware-in-the-loop ground testing. This ability to quickly field new or modified flight control systems for UAV's is of ever increasing importance as Department of Defense places greater emphasis on the use of UAV's in widely varying mission areas. The primary focus of this thesis is on the design and testing of a heading controller. However, to fully integrate this into the FMS, the research and testing includes airspeed and altitude controllers designed by previous thesis students. Also included as part of the implementation process, is a thorough sensor evaluation to ensure the controller inputs are adequate to support the FMS. The design and test equipment include a highly modified FROG UAV from the U.S. Army, the MATRIX Product Family of software tools developed by Integrated Systems, Inc., and a Ground Station built at NPS from commercially available computer and communication equipment.
