6. Center for Adaptive Aerospace Technology Traditional approaches to shape control use discrete transducers and lumped parameter modeling techniques e.g. finite element For real-time shape control these techniques can only address performance measures in a limited fashion, if at all Distributed Parameter Control – the control of systems described by space and (usually) time, can more effectively address spatial performance requirements

7. Center for Adaptive Aerospace Technology In addition to traditional temporal bandwidth requirements: Shape control requires both a prescribed spatial bandwidth and a set of shapes that characterize the control task, e.g. airfoil, wing and engine inlet shapes for efficient flow control Distributed Parameter System Control techniques and Spatially Distributed Transducers are well suited to the design and implementation of dynamic shape control in modern systems

Center for Adaptive Aerospace Technology What: Design, build, and demonstrate a seamless, aerodynamically efficient, aerial vehicle capable of: radical shape change Why:The ability to change the critical physical characteristics (aerodynamic shape) of the Vehicle in flight would enable/allow a single vehicle to: perform multiple mission profiles How:Distributed Parameter System control techniques and spatially distributed transducers: are well suited to the design and implementation of dynamic shape control in modern systems

13. Center for Adaptive Aerospace Technology Given the success and availability of temporal frequency domain tools in classical and robust, multi- variable lumped parameter systems control theory: The introduction of spatial frequency transforms to distributed parameter systems and control follow naturally! Using MIMO techniques one can construct an input/output relation representing a DPS in a temporal and spatial frequency domain
