Title:Adaptive Suppression of Frequency Varying Disturbances for an Oscillating Steel PlateAuthor(s):Andre Kreuzriegler, Engelbert Grünbacher, Lukas MessnerAbstract:Many industrial processes - from continuous casting to combustion engines - are subject to disturbances with periodic or almost periodic characteristics in the sense that the frequency and the amplitude may change with time. A specially interesting case is presented by bodies which can produce or transmit a large range of vibrations. In this paper we discuss the asymptotic suppression of such disturbances using an internal model approach and a frequency estimation algorithm. The effectiveness of the algorithm is demonstrated by its application to a single force oscillating steel plate, an experimental setup which confers the suitability of the approach.Booktitle:17th IEEE International Conference on Control Applications (CCA)Page Reference:6 page(s)Publishing:2008
