andrea-lafflitto-a-mathematical-perspective-on-flight-dynamics-and-control-book

 

Dr. Andrea L’Afflitto has recently published a new book titled A Mathematical Perspective on Flight Dynamics and Control. The book provides a mathematically rigorous description of flight dynamics complementing those presented from a physical perspective.

About this Book

This brief presents several aspects of flight dynamics, which are usually omitted or briefly mentioned in textbooks, in a concise, self-contained, and rigorous manner. The kinematic and dynamic equations of an aircraft are derived starting from the notion of the derivative of a vector and then thoroughly analyzed, interpreting their deep meaning from a mathematical standpoint and without relying on physical intuition. Moreover, some classic and advanced control design techniques are presented and illustrated with meaningful examples.

Distinguishing features that characterize this brief include a definition of angular velocity, which leaves no room for ambiguities, an improvement on traditional definitions based on infinitesimal variations. Quaternion algebra, Euler parameters, and their role in capturing the dynamics of an aircraft are discussed in great detail. After having analyzed the longitudinal- and lateral-directional modes of an aircraft, the linear-quadratic regulator, the linear-quadratic Gaussian regulator, a state-feedback H-infinity optimal control scheme, and model reference adaptive control law are applied to aircraft control problems. To complete the brief, an appendix provides a compendium of the mathematical tools needed to comprehend the material presented in this brief and presents several advanced topics, such as the notion of semistability, the Smith–McMillan form of a transfer function, and the differentiation of complex functions: advanced control-theoretic ideas helpful in the analysis presented in the body of the brief.

A Mathematical Perspective on Flight Dynamics and Control will give researchers and graduate students in aerospace control an alternative, mathematically rigorous means of approaching their subject.

About the Author:

The author is an assistant professor at the School of Aerospace and Mechanical Engineering of The University of Oklahoma and is presently teaching a graduate course in flight control. Dr. L’Afflitto holds a B.S., M.S., and Ph.D. degree in aerospace engineering and an M.S. degree in Mathematics and his research is currently focused on optimal control theory and differential games theory with applications to aerospace control problems, such as fuel-optimal path planning and formation flying.

A group of students from Dr. Andrea L’afflitto’s Flight Controls class created the following video:

According to Dr. L’afflitto, this project consisted of designing an autopilot for a quadrotor using some modern, very aggressive control techniques. The purpose of this video is to show the results achieved graphically, however, the mathematical models, the control design problem and the numerical simulations have very deep roots.

“I am extremely proud of their work because these are all undergraduate students, but the quality and the mathematical complexity is the one of a graduate project,” said Dr. L’afflitto. “We all can imagine the impact of the development of such technology, considering the growing attention that OU is putting on the UAS technology.”

Video Transcript:

This video shows the result of a students’’ project developed as part of the AME 4513/5513 “Flight Controls” course at the University of Oklahoma in Fall 2016. A DJI F450 will inspect some buildings of OU’s main campus. The drone’s autopilot implements an algorithm based on Model Reference Adaptive Control.

An important feature of this simulation is that the quadrotor dynamics is not captured by a set of nonlinear differential equations, but it is deduced from a SimMechanics model of a DJI F450. This guarantees high accuracy of the results presented.

The adaptive control technology allows precise, aggressive maneuvers in the vicinity of obstacles, such as buildings.

[VIDEO]

Next, we compare the performance of a quadrotor (in white) implementing an adaptive control law and a quadrotor (in black) implementing a classic PID controller.

Dr. Michael Zavlanos visited AME on February 2, 2017 as part of Dr. Andrea L’Afflitto’s Dream Course, Modern Control Theory and Applications.

Abstract: Current robotic systems have the potential to accomplish a previously intractable scope of tasks. Their ever growing capabilities will soon allow them to operate autonomously outside the lab, in remote, unpredictable, and uncertain environments, where the presence of humans is dangerous or even impossible. For this to become possible, a fundamental challenge is to develop new methods that will enable teams of robotic sensors to collaboratively explore unknown environments and extract concise actionable information. In this talk,we present a novel approach to dynamically synthesize optimal controllers for a robotic sensor network tasked with estimating a collection of hidden states. The key idea is to divide the hidden states into clusters and then use dynamic programming to determine optimal trajectories around each hidden state as well as how far along the local optimal trajectories the robot should travel before transitioning to estimating the next hidden state within the cluster. Then, a distributed assignment algorithm is used to dynamically allocate controllers to the robot team from the set of optimal control policies at every cluster. Compared to relevant distributed state estimation methods, our approach scales very well to large teams of mobile robots and hidden vectors. We also present a distributed state estimation method that allows mobile sensor networks to estimate a set of hidden states up to a user-specified accuracy. This is done by formulating a LMI constrained optimization problem to minimize the worst case state uncertainty, which we solve in a distributed way using a new random approximate projections method that is robust to the state disagreement errors that exist among the robots as an Information Consensus Filter (ICF) fuses the collected measurements. To our knowledge, even though the distributed active sensing literature is well-developed, the ability to control worst-case estimation uncertainty in a distributed fashion is new. We present numerical simulations and experimental results that show the efficiency of the reposed methods.

Bio: Michael M. Zavlanos received the Diploma in mechanical engineering from the National Technical University of Athens (NTUA), Athens, Greece, in 2002, and the M.S.E. and Ph.D. degrees in electrical and systems engineering from the University of Pennsylvania, Philadelphia, PA, in 2005 and 2008, respectively. From 2008 to 2009 he was a Post-Doctoral Researcher in the Department of Electrical and Systems Engineering at the University of Pennsylvania, Philadelphia. He then joined the Stevens Institute of Technology, Hoboken, NJ, as an Assistant Professor of Mechanical Engineering, where he remained until 2012. Currently, he is an assistant professor of mechanical engineering and materials science at Duke University, Durham, NC. He also holds a secondary appointment in the department of electrical and computer engineering. His research interests include a wide range of topics in the emerging discipline of networked systems, with applications in robotic, sensor, and communication networks. He is particularly interested in hybrid solution techniques, on the interface of control theory, distributed optimization, estimation, and networking. Dr. Zavlanos is a recipient of the 2014 Office of Naval Research Young Investigator Program (YIP) Award, the 2011 National Science Foundation Faculty Early Career Development (CAREER) Award, as well as Best Student Paper Awards at GlobalSIP 2014 and CDC 2006.

lauren-woodbury_x

Lauren Woodbury graduated from AME in 2014 with a B.S. in Mechanical Engineering. She is originally from Yukon, OK and is now living in Royal Oak, Michigan. Ms. Woodbury is currently working as an entry-level engineer at Isuzu Technical Center of America and pursuing an M.S. in automotive engineering part-time at the University of Michigan.

“I really like working on cars, because I like working on things that move. I like working with parts,” said Ms. Woodbury. “While I do sit at a desk and work on engineering-related studies, I also get to go out to the garage and look at the actual cars and help with the salvation team if there is any kind of information they need from engineering, I can go see whatever it is they are working on. I also get to do field investigation with customs or dealerships.”

While at AME, she participated in the Sooner Racing team and Sooner Off Road team. As a part of these teams, Ms. Woodbury had opportunities to work with other students and participate in class, and group problems and projects.

Ms. Woodbury’s family truly influenced her decision to pursue a career in engineering:

I enjoyed watching motorsports with my dad on the weekend. I really liked visiting grandparents in KS because they owned an automotive shop where they worked on vehicles for customers and also focused on rebuilding and refurbishing classic vehicles. I got to work on vehicles from the 60s and 20s. I was able to see how different they were from the vehicles today. It seemed the assembly of the vehicle was simple, but once I started taking it apart, there are a lot more pieces than imagined and it is really not that easy.

In her spare time, she enjoys exploring and traveling around Michigan. Ms. Woodbury is a fan of the OKC Thunder and Detroit Lions. Also, she enjoys motorsports.

 

 

AME-pre-capstone-1

The course consisted of different terrains and obstacles.

Throughout the fall semester, students taking the pre-capstone AME course, “Principles of Engineering Design” worked on a project that led up to a final performance test. The problem description is created out of a fascinating anthology of problems.

AME-pre-capstone-5

The students prepped the robots at the starting line.

The students’ task was to design, build and test a robot that has the ability to travel through an obstacle course and end by piercing a Styrofoam board, hopefully popping the balloon housed underneath. The teams were given 2 attempts to complete both aspects of the task with an optional 5-minute break to fix their robot or make alterations.

AME-pre-capstone-2

Chris Sanders, Pamela Duarte, Dallas Milligan, and Ian Wright choose to take time to fix their robot before their 2nd attempt at the course.

 

Each team consisted of a group of 4-5 interdisciplinary engineering students, ranging from mechanical to petroleum.

 

AME-pre-capstone-3

According to Senior Mechanical Engineering student Ciore Taylor, the class consisted of lessons about the design and planning phases. Teams initially determined the different skills each person in the group had, then moved on to coming up with different designs, then come to conclude the design process. Students were encouraged to use their imagination when coming up with the designs of the robot.

AME-pre-capstone-4

The winning teams were announced after each team had the opportunity to test their robots. precapstone-winners-ameprecapstone-winners-ameprecapstone-winners-ame precapstone-winners-ame

vanguard-award-winner-nsbeCongratulations to Salomon Rodrigue Mbouombouo! As a member of the National Society of Black Engineers, he was awarded the Region V 2016 Vanguard Awards: Academic Excellence Outreach Award. This award is given to students that show great academic achievement, academic profile, and community involvement.

ame-glider-2Dr. Thomas Hays’ Introduction to Aerospace Engineering course tested their model gliders in the Armory on Thursday, December 1, 2016. The student teams choose whether they wish to compete for either range or endurance and then they must predict how far or for how long it will fly.

 

ame-glider-1

“It is nice to be able to apply what you have been learning all semester to something as fun as constructing your own glider and testing it,” said Ryan Tullius (pictured left).

 

ame-glider-3 The students had the option to make the gliders out of any materials they want. Some of the common materials used were paperclips, balsa wood, and tape. Many students decorated their glider with different themes as well to represent each team.ame-glider-4

keith-walters-bioDr. Keith Walters was awarded $37,363.00 for his research project titled “Multiphysics Simulations of Multi-Component, Off-Design Aircraft Engine Operation Using Dynamic Hybrid RANS/LES.”

The grant is a subcontract from ATA Engineering, Inc., in collaboration with the Air Force Research Laboratory and Mississippi State University, funded under the Department of Defense High Performance Computing Modernization Program (HPCMP), specifically the HPCMP Applications Software Initiative (HASI) Project. They are working to develop enhanced computational fluid dynamics (CFD) models and algorithms to improve the prediction of flow and combustion in high-speed aircraft propulsion systems. Their focus at OU is the modeling and simulation of fluid turbulence. The team will be implementing newly developed models into the CFD software Loci-CHEM and providing the new tools to their collaborators at ATA and AFRL. This is the first year of a potentially four year project, subject to project progress and funding availability. The research group is hopeful to be awarded Year 2 funding.

nsbe-carouselThe GCoE National Society of Black Engineers (NSBE) is rebranding who they are and what they represent during the 2016-2017 academic school year. This year’s campaign is titled “The Re-Brand Year” and NSBE is specifically focusing on membership retention, professional development, academic excellence and strengthening the black engineering community.

On November 11-13, the OU NSBE chapter traveled to Houston, TX for the Fall Regional Conference (FRC). Their trip was extremely successful and we’d like to take a moment to share details of their experience with you.

To begin, the OU NSBE chapter exists within Region 5out of 6 total regions. Within Region 5, there are 32 chapters and a total of 1083 students attended FRC this year. Forty-three OU students traveled to FRC. The OU NSBE chapter brought the most students to the conference and this is a record number of attendees in GCoE NSBE history. Of the 43 students, 38 students maintained over a 3.0 GPA

During this trip, our chapter increased our participation in daily events offered and demonstrated great professionalism. As a reward for timeliness, professional dress and for being noticeably engaged in comparison to other chapters, the OU chapter was given exclusive access to the career fair ahead of 1000+ other students. We had several students receive interviews.

nsbe-carousel-2Not only did we participate as a chapter in larger events, we also had 3 students compete in the Elevator Pitch Competition, 4 students in the NSBE Debaters Competition, 7 students in the Academic Bowl, and 6 students in the Talent Show. Witnessing “The Re-Brand Year” take effect beyond OU’s campus was amazing and it was even more amazing to watch our chapter compete well against other universities.
