Eleventh Conference on Active Noise and Vibration Control Methods, 26–29 May 2013, Krakow-Rytro, Poland: Part-2

Abstract

The Conference on Active Noise and Vibration Control Methods has already had a twenty-year tradition. The conference aim is to present the results of recent research work, to exchange ideas and to share experiences with representatives from international research centres. The control of low frequency noise and vibration has always proved to be a difficult task and in many cases not feasible at all due to the long acoustic wavelength involved. If passive techniques were only considered, noise control would require large mufflers, heavy enclosures and flexible isolation systems or perhaps extensive structural damping treatment would be needed for vibration control. Active noise and vibration control methods involve the use controllable systems to reduce the transmission of vibration from one plant or structure to another. The Conference organized by the Department of Process Control AGH University of Science and Technology is held every two years. The major research areas include: active and semi-active methods of vibration control, active noise control, applications of smart materials and structures and control of noise and vibration parameters. It seems that the application of smart materials for active noise and vibration control methods has emerged as a regular theme of the meetings. The “School” held for the first time in 1993 was transformed into a Conference in 2003 and was named: Conference on Active Noise and Vibration Control Methods. This special section is the second of a two-part report on selected papers that appeared in the 11th Conference on Active Noise and Vibration Control Methods. The papers were extended by authors and placed into the rigorous review process of the Journal of Low Frequency Noise, Vibration and Active Control before acceptance. The conference featured technical scientific sessions of oral and poster presentations, divided into five sections, namely Active Vibration Control, Semiactive Vibration Control, Active Noise Control, Structural Control, and Smart Structures. The conference was held in Rytro which is uniquely situated on the edge of the Poprad River Natural Park, in one of the Southern Poland’s loveliest Mountains Beskid Sadecki. The conference was bundled with a bigger 14th International Carpathian Control Conference the focus of which is on the area of automatic control. Nearly 150 delegates participated in both conferences, and there were a total of 125 presentations given. The 11th Conference on Active Noise and Vibration Control Methods attracted the traditional number of nearly 60 delegates. The opening presentation was given by Stephen P. Banks describing “The global theory of nonlinear systems”. The second plenary lecture was given by Piotr Cupial/ who discussed the “Lord Rayleigh’s impact on vibration theory (From the past to smart structures)”. The technical sessions of the conference followed these two plenary presentations. Below is a brief description of the papers that feature in this second part report. Mateusz Koziol presented a problem of the active control of a Jeffcott rotor with the rotational speed in the supercritical range. He discussed application of
