Abstract

An aerodynamically and elastically scaled half span wind tunnel model of a SensorCraft configuration was tested in the Langley TDT wind tunnel to explore the aeroelastic control implications of SensorCraft. The wind tunnel model was mounted on a pitch and plunge device to allow the model to ‘fly’ in the wind tunnel. This paper presents the LQG (Linear Quadratic Gaussian) control design philosophy as well as the results from the SensorCraft wind tunnel model experiment. LQG control design was chosen as one of the methods used to design controllers for the wind tunnel model because it is a quick way to design controllers with complex and changing models. This test builds upon the previous HiLDA test of a SensorCraft model also done at the Langley TDT.
