Smart beam system: Identification and minimal realization using digraphs theory

For modelling the dynamics and study of the active vibration suppression possibilities in aircraft wings, the smart beam is widely used. The advantages obtained through this approach are numerous. One of them are: aircraft stability and manoeuvrability, turbulence immunity, passenger safety and reduced fatigue damage. In this paper, the identification process has been presented, in the first step. As a result the transfer function of the continuous-time linear system was given. Then, for the obtained function the forms of minimal realizations were determined. The realization was obtained using the method based on one-dimensional digraph theory.
