Bio

Dr. Agamemnon Crassidis is a Professor in Mechanical Engineering at the Rochester Institute of Technology. He received his B.S., M.S., and Ph.D. in Mechanical Engineering from the State University of New York at Buffalo specializing in control systems engineering and systems design and dynamics. His Ph.D. dissertation research was focused on the nonlinear control a motor-flexible beam system with nonlinear friction. Specifically, he developed and analyzed mathematical models for a slewing motor-beam system with the inclusion of nonlinear friction and extended these models to multi-link flexible robotic manipulators. He has more than 17 years of industrial experience in the areas of aerospace flight control system design; aircraft parameter identification; mathematical modeling and identification of nonlinear systems using experimental responses; systems engineering; mechanical systems design; and navigation, control, and measurements systems. Dr. Crassidis' current research focuses on the development of advanced all attitude/orientation devices, inertial movement correction algorithms, orientation and center-of-gravity estimation for aircraft, and model-free nonlinear control law development. He is the author of nearly a dozen papers on the topic of alternate next-generation inertial navigation and orientation sensing systems using advanced correction algorithms, CG estimation, and nonlinear model-free sliding-mode controller applications. He is an active member of the American Institute of Aeronautics and Astronautics serving as past Chair for the Atmospheric Flight Mechanics Technical Committee section and Academic Director for NUAIR (operator of the Northeast FAA UAS test-site).

3 Credits
This course introduces the student to methods used to design advanced nonlinear control systems. Topics of this course include: Phase-State Plane Analysis, Existence of Limit Cycles, Lyapunov Stability (Direct and Indirect methods), nonlinear control design using Feedback Linearization, the Sliding Mode Control method, Numerical Optimization of PID laws, and Adaptive Control strategies. Students are expected to complete computer projects using Matlab/Simulink.
MECE-411
3 Credits
This course introduces orbital mechanics and space flight dynamics theory with application for Earth, lunar, and planetary orbiting spacecraft. Content includes historical background and equations of motion, two-body orbital mechanics, orbit determination, orbit prediction, orbital maneuvers, lunar and interplanetary trajectories, orbital rendezvous and space navigation (time permitting). The two body orbital mechanics problem, first approximation to all exploration orbits or trajectories, is covered with an introduction to the three body problem. Students develop computer based simulations of orbital mechanics problems including a final mission project simulation from Earth to Mars and home again requiring a number of orbit phases and transfers between these phases.

ENGR-702
3 Credits
This course provides graduate students with the professional skills needed by PhD graduates within their major research focus area to move the results of their research from the lab into practice. Students will demonstrate a strong contextual understanding for their research efforts. Students will learn professional skills related to Teamwork; Innovation, Entrepreneurship and Commercialization; Research Management; Policy and Societal Context; and Technical Writing.
ENGR-795
1 Credits
This seminar course presents topics of contemporary interest to graduate students enrolled in the program. Presentations include off campus speakers, and assistance with progressing on your research. Selected students and faculty may make presentations on current research under way in the department. All doctoral engineering students enrolled full time are required to attend each semester they are on campus. (Graduate standing in a technical discipline)
