ABSTRACT: This
paper studies the problem of isochronal synchronization of chaotic systems with
time-delayed mutual coupling. Based on the invariance principle of differential
equations, an adaptive feedback scheme is proposed for the stability of
isochronal synchronization between two identical chaotic systems. Unlike the
usual linear feedback, the variable feedback strength is automatically adapted
to isochronally synchronize two identical chaotic systems with delay-coupled,
so this scheme is analytical, and simple to implement in practice. Simulation
results show that the isochronal synchronization behavior is determined by time
delay.
