Development of an active control system to suppress flutter using pressure feedback on a trailing edge control surface. The method uses finite element method for structural analysis, vortex-lattice method for non-stationary aerodynamics and surface spline interpolation for meshes coupling. System efficiency is obtained analyzing control gain value and sensor position.
