Abstract:

Control of systems described by large-order models typically requires construction and use of reduced order models ROMs for the purpose of feedback controller design and implementation. However, controllers based on these ROMs can have deleterious interactions with un-modeled modes, and some sort of stability compensation is needed, such as Residual Mode Filters RMFs. In this report we summarize our work on exponential closed loop stability using RMFs for Aero-Elastic Simulations. This can be achieved for systems with actuator dynamics, as well as for controllern designed only using a ROM of the actuator. Our applications include the control of fluid-structure interaction in a simple piston model and a three dimensional NACA wing to alleviate aero-elastic flutter.
