Query: Well-posedness of infinite-dimensional non-autonomous passive boundary
  control systems   We study a class of non-autonomous boundary control and observation linear
systems that are governed by non-autonomous multiplicative perturbations. This
class is motivated by different fundamental partial differential equations,
such as controlled wave equations and Timoshenko beams. Our main results give
sufficient condition for well-posedness, existence and uniqueness of classical
and mild solutions.
