Abstract

Abstract: This paper evaluates and compares data-based and analytic modelling for model- based active vibration control based on the performance of the closed loop system for a simply supported flexible beam. The thin beam is controlled utilizing collocated piezo patch actuators and sensors. An electrodynamic shaker introduces a disturbance force in the direction of oscillation. The data-based design plant is identified using N4SID. The analytically obtained design plant is based on a one-dimensional finite element (FE) model. The comparison of the two entirely different modelling approaches is validated using a variety of different optimal & robust multi-input multi-output (MIMO) control design methods.
