Theoretical modelling of active flutter suppression of plate components of aaerospace structure is presented. The equations governing the dynamics of thepanel, relating the strains in the piezoelectric elements to the strain induced inthe system, are derived for isotropic plates using the RayleighRitz method. Acriterion for optimal placement of piezoelectric actuators was suggested usingmodal controllability. The model was then used to find the optimal location forthe piezoelectric actuator utilizing genetic algorithms. The linear quadraticGaussian design method was used to stabilize the panel flutter using apiezoelectric actuator. This study clearly showed that the flutter can be delayedusing the piezoelectric actuator.
