摘要: The present work investigates feedback control of flutter using piezoceramic strain actuators. A two degree-of-freedom oscillating airfoil model with the air loads simulated assuming unsteady aerodynamics is considered. Various measurement combinations for SISO and actuation in heave pitch direction are studied to quantify their effect on flutter. sensor placement airfoil, combined feedback, also studied. results show that a given aeroelastic system, location an important parameter realizing increase speed. It demonstrated speed can be increased by more than 50% through direction.
