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