This paper presents a sufficient condition for the DHCD prob-
lem for nonlinear systems. The resulting controller guarantees local
asymptotic stability and provides a predetermined L2-gain bound on
the closed-loop system. Two design methods of the local observers
are given: one is based on the centralized observer gain and another
one is related to the solution of the matrix inequalities. The results
are extensions of those in  and  for the case of linear systems.
