Boundary controllability and source reconstruction in a viscoelastic string under external traction

Treatises on vibrations devote large space to study the dynamical behavior of an elastic system subject to known external tractions since usually a “system” is part of a chain of mechanisms which disturb the “system” for example due to the periodic rotation of shafts. These “disturbances” affect the horizontal component of traction in a time dependent way. s paper we shall study control and source identification problems for a viscoelastic string subject to external traction, using moment theory.
