Abstract

A crucial step in the control of a high-precision system is having a very accurate model of the system from actuators to sensors and to unmeasured performance variables. Finite Element (FE) dynamic models may be good candidates apart from the fact that the accuracy of these models is often too limited, since it is almost impossible to fully match with the real structure. Using a FE model updating algorithm the accuracy of a FE model can be significantly improved. In this paper, a Frequency Response Sensitivity (FRS) model updating algorithm is developed that updates the eigenvalues of the stiffness and damping matrx (so-called generic parameters) to update an increase the accuracy of the FE dynamic model. The algorithm is applied on a 2D pinned-sliding beam system.
