Abstract:
This paper presents a general method of the generalized projective
synchronization and the parameter identification between two
different chaotic systems with unknown parameters. This approach is
based on Lyapunov stability theory, and employs a combination of
feedback control and adaptive control. With this method one can
achieve the generalized projective synchronization and realize the
parameter identifications between almost all chaotic (hyperchaotic)
systems with unknown parameters. Numerical simulations results are
presented to demonstrate the effectiveness of the method.
