Abstract
Research in aeroelasticity composes a significant part on aircraft design. Aiming both safety and efficiency, vibration control mechanisms should be implemented for achieving better results. In this context, this work deals with active aeroelastic control using PID control theory. A tridimensional model of a uniform and rectangular wing is assumed to provide computational results. Strip Theory is used to model the aerodynamical behaviour, and the pk frequency match method provides the frequency and damping data in each flight condition. From the results, it is possible to observe that the gain of the controllers increases the flight envelope, and the increase of derivative gain has a higher influence when compared to proportional gain.
