As we have announced in the title of this work, we show that a broad class of linear evolution equations is exactly controllable. This class is represented by the following infinite-dimensional linear control system:

and
generates a strongly continuous semigroup operator T(t) according to Pazy. We give a necessary and sufficient condition for the exact controllability of this system and apply this result to a linear controlled damped wave equation.
Keywords: linear evolution equations; exact controllability; damped wave equation.
