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)
