Interpolatory-Based Data-Driven Pulsed Fluidic Actuator Control Design and Experimental Validation

Pulsed fluidic actuators (PFAs) play a central role in the fluid flow experimental control strategy to achieve better performances of aeronautic devices. In this brief, we demonstrate, through an experimental test bench, how the interpolatory-based Loewner data-driven control (L-DDC) framework is an appropriate tool for accurately controlling the outflow velocity of this family of actuators. L-DDC combines the concept of ideal controller with the Loewner framework in a single data-driven rationale, appropriate to experimental users. The contributions of this brief are, first, to emphasize the simplicity and versatility of such a data-driven rationale in a constrained experimental setup and, second, to solve some practical fluid engineers concerns by detailing the complete workflow and key ingredients for successfully implementing a PFA controller from the data acquisition to the control implementation and validation stages.
