  We show that global generalized synchronization (GS) exists in structurally
different time-delay systems, even with different orders, with quite different
fractal (Kaplan-Yorke) dimensions, which emerges via partial GS in
symmetrically coupled regular networks. We find that there exists a smooth
transformation in such systems, which maps them to a common GS manifold as
corroborated by their maximal transverse Lyapunov exponent. In addition, an
analytical stability condition using the Krasvoskii-Lyapunov theory is deduced.
This phenomenon of GS in strongly distinct systems opens a new way for an
effective control of pathological synchronous activity by means of extremely
small perturbations to appropriate variables in the synchronization manifold.
