Active control of panel flutter with linearized potential flow aerodynamics
This paper investigates the active control of panel flutter including linearized potential flow aerodynamics. The aerodynamic modeling is accomplished by approximating the aerodynamic generalized forces, as developed by Dowell with infinite impulse response (IIR) filters. These filters are coupled to the in vacuo panel dynamic system in feedback, thus, creating a coupled, aeroelastic system. A self-sensing piezoelectric actuator, as described by Anderson, et al., Dosch and Inman and more recently Cole and Clark, is used to implement direct rate feedback control. Results of an analytical implementation of this control system are presented.
