Abstract: In the aerospace industry, regulatory agencies establish validation and certification procedures to ensure safety against undesirable phenomena in aircraft and protect the physical integrity of occupants. An important trend in this sector is the use of flexible structures, which enhances aircraft maneuverability. However, this flexibility also makes aeroelastic phenomena, such as flutter, more pronounced. This study employs an aeroservoelastic model for the dynamic control of flutter using the Matlab-Simulink® platform. The model is based on PID control law, and the mathematical modeling considers a linear and homogeneous wing with a trailing-edge control surface. The research aims to explore the interaction between the control system and the aeroelastic system, focusing on specific objectives such as gain variations. The results are analyzed through graphical representations in the V-g-f space. This approach allows for an understanding of the control system's impact on aircraft performance, aiming for controlled and safe flight.
