Abstract: For the chaotic systems with failures, the samplebased chaos systems were converted into discretetime system by using the Euler approximate discretization approach. A mathematic model was established for a class of common faults, with the observer designed. The design method of the faulttolerant synchronization controller was given to achieve the synchronization of two chaotic systems, with the sufficient condition given for asymptotic stability of the error system. The controller gain was solved by LMI of Matlab. Synchronization of the two Chua’s circuits was realized by simulation. Compared with other algorithm, the effectiveness and the faulttolerant performance of the proposed method were illustrated.
