This article presents a new concept that can be used to explain the physical mechanism that causes flutter: the concept of the structural actuator and the effects of its saturation on the aeroelastic stability of an aircraft. One detailed physical mechanism that could be the caus...

Each dynamic mode (aeroelastic) is made up of torsional and rotational movements. These two movements in each mode were dissociated and the phase, amplitude, damping and frequency of each of these movements were analyzed. The structural resistances of torsion and bending, as wel...

Universal Integral Regulator (UIR) is a widely used control law for control problems, it is based on sliding mode control with the inclusion of a Conditional Integrator (CI). In the original approach of this control law, the main gain is considered a constant. The purpose of this...
