"Volterra Series: Modelling Limitations"

Back
Abstract:
Although the application of Volterra series has produced excellent results in the analysis of many real systems during the last decades, there are still many unsolved and challenging problems in this field. This talk briefly shows the limits of application of Volterra series in system modelling and proposes new solutions for some limitations. More emphasis is placed on convergence of the Volterra series and Volterra series modelling for systems with discontinuities or systems with subharmonics. Examples are given for modelling wave-forces and geomagnetic activity.

Biographical Sketch:
Dr. Otilia M. Boaghe received the engineering diploma in electronics and computer engineering from the Transilvania University, Brasov, Romania, in 1995, and the M.Sc. (with distinction) and the Ph.D. degrees from the University of Sheffield, Department of Automatic Control and Systems Engineering, U.K., in 1996 and 2001, respectively. She is currently employed as Senior IC Development Engineer at Philips Semiconductors, Zurich, Switzerland. Her research interests in the field of system engineering include nonlinear system analysis, Volterra series, system identification, spectral analysis, neural networks, wavelets, sub-harmonics, wave-force dynamics and geomagnetic activity. In the past years she gained experience in the IC design, digital and analog, in testing, verification and evaluation.
