Dr. Buckner is interested in modeling, analysis, and control of dynamic systems, electromechanical systems, manufacturing automation, intelligent control, mechatronics

Dr. Buckner teaches Design of Electromechanical Systems (MAE 535), a graduate course he introduced in 2000. This course reviews the fundamentals of electromagnetic (EM) theory and introduces the computational tools needed for EM design. During the last half of the semester his students complete industry-sponsored EM machine design projects.

At the undergraduate level, Dr. Buckner teaches Engineering Dynamics (MAE 208) and Principles of Automatic Control (MAE 435). In Engineering Dynamics he brings to class guest lecturers who use engineering dynamics in their work. His Principles of Automatic Control culminates in a “hands on” design project, where students apply modeling and simulation tools to develop controllers which are validated computationally and experimentally. Dr. Buckner uses his research videos to illustrate the power of control systems, like one of an off-road vehicle showing the dramatic improvements in ride quality that can be obtained using an active suspension system.

Dr. Buckner’’s research is interesting to students because it focuses on the development of technologies that address human health needs, because it balances mechanical and electrical systems design, and because of its “hands-on” nature. His students are engaged in research and development using theoretical, computational and experimental tools with a focus on technology transfer and commercialization. Dr. Buckner’s students tend to be independent, motivated and creative.

Outside of work, Dr. Buckner enjoys spending time with his family, working outdoors, fishing and hunting.
