D.Sc., Columbia University, 1976.

Research Areas: Dynamic systems and control, active vibration suppression, time delayed system stability and control, robust nonlinear controls, design for vibrating structures, control of multi-body systems, micro controls in bio-engineering applications.


Dr. Olgac joined the faculty of the Mechanical Engineering Department in 1981. He received his Doctor of Science degree from Columbia University in 1976. Prior to joining the department, he directed an industrial operation in radio, television, and home appliance manufacturing. His research focus is on time-delayed systems, vibration suppression techniques, nonlinear robust control of dynamic systems, and micromanipulation in cellular biology. On the stability of time delayed systems he has introduced a mathematical paradigm, called the Cluster Treatment of Characteristic Roots (CTCR). This paradigm has direct application in the fields of optimized high-speed machining and conventional digital feedback controls. Dr. Olgac also introduced a new concept of actively tuning vibration absorbers. This concept, called the Delayed Resonator (DR), resulted in three patents (1995, 1996 and 1999). In his work on nonlinear robust control of dynamic systems, he has developed advanced control algorithms for systems with uncertain dynamics using sliding mode control fundamentals. Dr. Olgac is currently developing new methodologies in time-delay management and systems with multiple unrelated time delays, optimal semi-active vibration control strategies, and nano-manipulative tasks in bioengineering. Prof. Olgac's research has been funded by DoE, NSF, NIH,ONR, NOAA, ARO, GE, Connecticut Innovations Inc., Pratt and Whitney, Sikorsky, and other industry. Dr. Olgac was a guest professor at INRIA (France; 1988 -- 89) the Technical University of Munich (1995 -- 96) and Harvard University (2002 -- 03). He is a Fellow of ASME and Senior Member of IEEE, Executive Committee Member (and Past Chair) of ASME-Dynamic Systems and Control Division, an Associate Editor of the ASME Journal of Dynamic Systems, Measurement and Control, Member of the Editorial Boards of International Journal of Mechatronics and Manufacturing Systems, and Journal of Vibration and Control.
