The project focuses on the
developments of methods for reducing flowinduced cavity
resonance using active flow control integrated with feedback control.
The systematic integration of feedback control and active
openloop flow control requires a method for developing a
model that captures the dynamics of the relationship between the inputs
(the actuators) and the characteristics of the flow to be controlled,
but is at the same time tractable from the point of view of the design.
Order reduction techniques are employed to reduce the order
of the system described by the NavierStokes equations, a system
of nonlinear partial differential equations, to a system modeled by a
much smaller set of ordinary differential equations. The
reduced order model is then used in the design of
modelbased feedback control laws. Preliminary results and research
directions are reported in [1], [2].
