Abstract�� The panel flutter phenomenon with thermal effect was researched. By virtue of von Karman-s large deflection plate theory, piston theory aerodynamics and the quasi-steady thermal stress theory, the aeroelastic model of composite panel with embedded piezoelectric materials was established. In nonlinear finite element equation the Bogner-Fox-Schmit element was adopted. The dynamic equations of motion were transformed into a state space model in order to design controller. An optimal controller based on the nonlinear model was presented. The flutter suppression results in the time domain using the Runge-Kutta method for a simply supported piezolaminated composite panel subjected to uniform thermal loading was realized. The effectiveness of the present control method was illustrated by simulation solution.
Keywords�� panel flutter   piston theory   thermal stress theory   finite element method   piezoelectric materials
