Fund Project: This research was supported by the Austrian Science Fund (FWF) under Grants No. P24301 and No. P29177.

Dynamical canonical systems and their connections with the classical (spectral) canonical systems are considered. We construct Bäcklund-Darboux transformation and explicit solutions of the dynamical canonical systems. We study also those properties of the solutions, which are of interest in evolution and control theories.

Keywords: Dynamical canonical system, canonical system, Hamiltonian, Bäcklund-Darboux transformation, explicit solutions, energy, $C_0$-semigroup, well-posedness.
