Design of Adjoint Based Laws for wing flutter control
Design Adjoint Based Laws wing fl utter control
2015/7/2
An airplane, by its nature of being, is constructed so that it is as light as possible. The structural design is guided by static and dynamic factors. The more stringent constraints on the structural ...
Optimal Control of LCOs in Aero-Structural Systems
Optimal Control LCOs Aero-Structural Systems
2015/7/2
Aero-elastic systems, by their very nonlinear nature, frequently encounter Limit Cycle Oscillations (LCOs). An LCO occurs when the system being described reaches a periodic steady state where there is...
Flutter is one of the most frequently encountered problems in aeroelasticity. Flutter control is therefore of great importance. It has been shown that flutter can be adequately modeled using a s...
