Computational Analysis of the Active Control of Incompressible Airfoil Flutter Vibration Using a Piezoelectric V-Stack Actuator

The flutter phenomenon is a potentially destructive aeroelastic vibration studied for the design of aircraft structures as it limits flight envelope aircraft. aim this work to propose heuristic piezoelectric actuator-based controller suppression in order extend allowable speed range structure. Based on numerical model three degrees freedom (3DOF) airfoil and taking into account FEM V-stack actuator, filtered PID tuned using population decline swarm optimizer PDSO algorithm, gain scheduling (GS) parameters used make control adaptive velocity. Numerical simulations are discussed study performance presence external disturbances.
