The present work deals with active vibration control on lightweight structures subject to periodic excitations in fluid-structure interactions. For this purpose partitioned schemes for co-simulation of computational fluid-structure-control interaction are developed and implemented. They are subsequently investigated in numerical experiments. In addition, different closed-loop control laws are derived and employed.
Thus, this work essentially covers two aspects: First, convergence and stability properties as well as numerical effort of the proposed schemes are analyzed. This is supported by investigations on a model problem within the Honours Project. Second, the effectiveness of the previously established closed-loop control laws is assessed.
Honours Project
A simple coupled model problem is developed and iteratively solved using fixed-point formulations for different Gauß-Seidel communication patterns. Convergence and stability properties of the resulting solution algorithms are analytically assessed. The results allow predictions on corresponding partitioned schemes (co-simulation) for computational fluid-structure-control interaction. The Honours Project mainly covers Chapter 3 Model Problem (pp. 32–51) as well as parts of Chapter 9 Fluid–Structure–Control Interaction (pp. 118–160) of this work.
