Abstract: Flow control is the notion of manipulating the evolution of a fluid flow to achieve a desired outcome using passive or active means. Flow control technologies can enhance performance and efficiency in engineering systems, ranging from airplanes to underwater robots to wind turbines. 听Ongoing efforts aim to improve the reliability and performance of these systems by 鈥渇eeding back鈥 sensed information about the evolution of a flow to determine how to actuate the flow in an optimal manner. Achieving effective flow control often requires reliable and efficient models for the complex dynamics of fluid flows; estimators that can infer knowledge about the evolution of these flows from a limited set of sensor measurements; and control policies and algorithms that use these inferences to actively and reliably manipulate the evolution of fluid flows to achieve specified performance objectives. 听This talk will provide an overview of past and ongoing research related to the various modeling, analysis, and design challenges associated with controlling flow interactions in aerodynamic systems. 听Focus will be given to how control theory, system dynamics, optimization, and applied mathematics can be used to reveal essential flow interactions and harness them to achieve a performance benefit.
