Parameter identification and synchronization of spatio-temporal chaotic systems with a nonlinear observer

This paper presents a new approach to synchronize spatio-temporal systems including parametric identification as goal. The paper concentrates on generalized synchronization with a so-called Master-Slave (unidirectional) topology. The approach deals with the construction of a nonlinear observer to estimate the parameters of a Master system, such that the estimates can be used on-line by a Slave system to synchronize with the Master. Both, the Master and the Slave system, are approximated by the Finite Difference Method.
