Computational Closed-Loop Control of Fluid-structure Interaction (FSCI) for Lightweight Structures

This contribution gives a short introduction into the topic of fluid-structure-control interaction (FSCI). This is a multi-field problem, where three fields are coupled, namely a fluid-flow, structural dynamics and closed-loop control of structures. The interactions are identified as surface-coupling of fluid flow and structural dynamics as well as signal-coupling of structural dynamics and closed-loop control.

At first a simple model problem is introduced, which allows an efficient investigation of the convergence behavior and stability of such kind of problem. In this context an iterative partitioned approach, using a serial Gauß-Seidel scheme, is presented. Finally, the insights gained by the model problem are used to set up a multi-dimensional numerical experiment. (© 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
