Abstract :
Single piezo ceramic element (PZT) was introduced to a wind tunnel wing model for active flutter suppression. The wing modeling process using FEM analysis for structures and doublet point method for aerodynamics was described. As an extension to the previous experimental research with a proportional control, the LQG flutter suppression control law design based on the modeling equations was presented. The LQG control law was verified in wind tunnel tests in air and turned out to be able to successfully control the flutter
