Chapter 5 Dynamic and Closed-Loop Control
cwrowley.princeton.eduThis ability of feedback systems to modify a system’s natural dynamics is discussed further in Sections 2.1 and 4.5. Only recently have closed-loop controllers been used in flow control applications. Our objective here is to outline the main tools of control theory relevant to these
