The undergraduate level textbook titled “Flight Dynamics and Control of Aero and Space Vehicles” was published by Wiley in Feb 2020. Currently he is under contract with AIAA Education Series in authoring a third textbook titled "Robust Control of Aerospace Systems: A State Space Approach" to be completed by Aug 2021.
He served as the Chair of the Technical Program Committee for the 2015 ASME Dynamic Systems Control Conference. He currently serves as a member of the Honors and Awards Committee of the ASME Dynamic Systems and Control Division (DSCD) in charge of selecting candidates for high profile awards such as the Oldenberger Medal, Paynter Award and Kalman Best Paper awards etc. He was the Society Review Chair for AIAA for the American Control Conference for 2015. He was an Associate Editor for the ASME Journal of Dynamic Systems, Measurement and Control (2006-2013) as well as the International Journal of Systems Science (1992- 2012). He is also a member of the Conference Editorial Board (CEB) for IEEE and ASME. He co-edited an IEEE Press Book on "Recent Advances in Robust Control" in 1990 which enjoys high citation in many research papers. He also served as an Associate Editor for the AIAA Journal of Guidance, Control and Dynamics (1992-95). He was the Chairman of the Technical Program Committee for the 1991 AIAA Guidance, Navigation and Control Conference held in New Orleans, LA. He offered tutorial workshops on "Robust Control" at the 1992 IEEE Conference on Decision and Control and the AIAA GNC Conference and for Ohio Aerospace Institute. He was a member of the technical program committees for the 1992 American Control Conference and IEEE Conference on Control Applications. He served as the Society Review Chairman for the 1993 ACC. He served as a member of the AIAA Technical Committee on Guidance, Navigation and Control during 1989-1992. He is a member of the IFAC working Group on "Robust Control" and was a member of the IEEE working group on Linear Multivariable Systems. He organized, chaired and co-chaired (and continues to do so) various technical sessions in conferences such as ACC, CDC, CCA and AIAA GNC. He serves as a reviewer for many journals , conferences and NSF (including being a member of different Panels for NSF and ONR). He served as a "Guest Editor" for a special issue in the Journal of "Mathematical Problems in Engineering" . He was a consultant to the Lawrence Livermore National Laboratory for two years.
He has been and continues to be very active in his service to his Department, College and University at OSU. He served as the Chairman of the College P&T Committee, prior to which he was a member of the College P&T Committee, Chair of the MAE Department P&T Committee as well as a member of that committee. Currently, he is a member of the MAE department's Honors and Awards committee, being in charge of the internal College awards. He is also a member of various Faculty Search Committees, having already served as the Chairman of the Undergraduate Studies Committee in the former Aerospace Engineering Department. He was a candidate for the Head of the former Aerospace Engineering department as well as for the MAE department in 2011. At University level, he served as a member of the University Fellowship Evaluation committee.
With the support of his extensive sponsored research, Dr. Yedavalli graduated several Master’s and Ph.D students (including a Post Doctoral researcher) who are all well placed professionally (at Industries like GM, Boeing, P&W and Universities like Cal State, Long Beach). One of his Ph.D graduates, Dr. Praveen Shankar, during his Ph.D tenure with Dr. Yedavalli, upon his nomination, won the prestigious AIAA Foundation’s Orville Wright Graduate Student Award in 2006. Another Ph.D graduate, Dr. Rohit Belapurkar (Ph.D, Autumn 2012) was the Winner of few AIAA Student Best paper awards and recently Grand Prize Winner in the AIAA New Horizons Contest, along with the Best Reviewer award by the International Journal of Systems Science and recipient of an ASME IGTI Scholarship. Another Ph.D graduate Dr. Nagini Devarakonda (Ph.D, Summer 2011) was a semi-finalist in the Student Best paper award contest in the American Control Conference as well as Best Session Presentation award, and was a winner of the Outstanding Achievement award by the WIE section at OSU. His former Masters' thesis advisee, Ms. Sampriti Bhattacharyya completed her doctoral degree at MIT and she was selected as one of the Forbes Under 30 innovators.
In addition, he presented a short course on `Sensitivity of Dynamic Systems’ for faculty members at the University of Julia in Maracaibo, Venezuela, presented a short course on `Robust Control’ for AIAA as a member of a team of instructors and presented an invited short course on `Robust Control of State Space Systems’ for IEEE.
Recently, the paper: R.K.Yedavalli, R.K.Belapurkar: “Application of Wireless Sensor Networks to Aircraft Control and Health Management Systems”, Journal of Control Theory and Applications, Special Issue: “Wireless Sensor Networks: from Theory to Practice”, Vol. 9, No.1, pp. 28-33, February 2011, was declared as the Top 5 Downloads of that journal.
Dr. Yedavalli's research and teaching interests include robustness and sensitivity issues in linear uncertain dynamical systems, estimation and fault diagnostics of propulsion systems, control of smart structural systems, dynamics and control of flexible structures with applications to aircraft, spacecraft, automotive, robotic, aerospace propulsion and other mechanical systems control. He published close to 200 Journal, Book chapters and Conference papers and presented invited seminars on these topics.
He carried out research for Small Businesses under the SBIR/STTR route. His entrepreneurship efforts include serving as the President of "Robust Engineering Systems, LLC" which carried out research as a subcontractor for few projects from Air Force and AFRL. His expertise on control systems design, flight vehicle autopilot design and robust control systems design are sought by various Industries.
