Abstract:

Research was conducted in identification and control of distributed parameter systems, particularly damping mechanisms in distributed elastic systems, modeling of flexible structures, control of systems with nonlinear behavior and control of systems with solitary waves. A thorough analysis if damping mechanisms in elastic systems was carried out, including common classical forms of damping, and led to a new model of damping spatial hysteresis which correctly models observed asymptotic behavior in the frequency domain. More recent work focused on transfer function methods for infinite dimensional linear systems. Papers included Some remarks on transfer function methods for infinite dimensional linear systems Spectral and asymptotic properties of linear elastic systems with internal damping and Frequencyperiod estimation and adaptive rejection of periodic disturbances.
