The open loop and closed loop tests for the joint MIT/NASA Langley Active Aeroelastic Wing project are summarized. Linear Quadratic Gaussian control laws are designed as well as laws using robustified design techniques such as sensitivity weighted LQG, classical rationalization, and multiple model. Significant vibration suppression and load alleviation is demonstrated, reducing the power spectral density of the response of the first mode by an order of magnitude. The flutter dynamic pressure is increased by 12 % using a single input/single output control law. The tests demonstrate that the three major performance limitations are the saturation limit of the piezoelectrics, the choice of performance metric or output sensor, and the changes in the dynamic response of the test article.
