Abstract: In this paper, we derive a new description form of coupled bending and torsional vibrating system with boundary control and observation through Green's formula and prove that it is equivalent to the original form. On the basis of this. we prove the control system is well-posed in time and frequency domain and completely controllable and observable.

Key words: Coupled bending and torsional vibrating system, Boundary control and obsevation, ball-posedness
