We report the synchronization of two nonidentical spatially extended fields
, ruled by one-dimensional complex Ginzburg-Landau equations. The two field
s are prepared in different dynamical regimes, and interact via an imperfec
t coupling consisting of a given number of local controllers N-c. The stren
gth of the coupling is ruled by the parameter epsilon. We show that, in the
limit of three controllers per correlation length, the synchronization beh
avior is not affected if the product epsilonN(c) /N is kept constant, provi
ding a sort of integral behavior for localized synchronization.
