AB  - The research unit FOR 1779 develops robust methods for the reductionof turbulent friction drag via wavy surface oscillations. For this research,wind tunnel experiments with a Lorentz force actuator system producingtraveling surface waves are conducted. An improved version of the systemnecessitates feedback control that is designed based on iterative learningcontrol and verified in reference tracking and wind tunnel measurements.Due to thermal limits the design does not reach the desired parameters.A new design is optimized with the help of numerical methods and a firstprototype reaches the desired parameters.
