A Systems-Theory Approach to Flow Control

该项目旨在为反馈流控制提供一个通用的控制理论基础，该基础是鲁棒的，并且明确认识到与当前驱动技术相关的局限性，例如要求所有驱动和传感都在壁上执行。长期目标是在布满传感器和执行器的表面上控制流量。这些传感器将收集基于实时反馈控制的精确控制决策所需的信息。表面执行器将用于改变流量并使其恢复到所需的状态（层流）。嵌入式传感器通常会测量表面力（剪切和压力），而驱动可能是可变形表面（一组凹窝）、各种类型射流的表面蒸发量或电磁力。

This project aims to deliver a general control-theoretical foundation for feedback flow control that is robust and which explicitly recognises the limitations associated with current actuation technologies, such as the requirement that all actuation and sensing is performed at the wall. The long-term goal is to control flows over a surface densely carpeted with sensors and actuators. These sensors will gather the kind of information required to make accurate control decisions based on real-time feedback control. Surface actuators will be used to alter the flow and bring it back to a desired state (of laminar flow). An embedded sensor will usually measure surface forces (shear and pressure) while actuation might be a deformable surface (an array of dimples), surface transpiration from jets of various types or electromagnetic forcing.
