In this paper, a learning control approach is applied to
the generalized projective synchronisation (GPS) of different
chaotic systems with unknown periodically time-varying parameters.
Using the Lyapunov--Krasovskii functional stability theory, a
differential-difference mixed parametric learning law and an
adaptive learning control law are constructed to make the states of
two different chaotic systems asymptotically synchronised. The
scheme is successfully applied to the generalized projective
synchronisation between the Lorenz system and Chen system. Moreover,
numerical simulations results are used to verify the effectiveness
of the proposed scheme. 相似文献
