Synchronization of Uncertain Chaotic Systems Based on Robust Control

The synchronization issue of two uncertain chaotic systems is investigated.Parameters of a chaotic system will vary in a given scope if there are some external disturbances,and then the uncertainty is introduced.The model of two intercoupling uncertain chaotic systems is studied.Based on robust control,a synchronization scheme is proposed.Using the Lyapunov-Krasovskii stability theorem and linear matrix inequalities(LMIs),the scheme developed here is proved to be effective.Finally,we take the Chua's circuit for illustration and verification.
