The problem of master-slave fault tolerant synchronization for a class of chaotic systems with multiple time-delays is considered. A fault tolerant synchronization is designed for a fault occuring in chaotic systems. Whether the fault happens in the chaotic systems or not,the synchronization method not only guarantees that the error system is globally asymptotically stable,but also satisfies a prescribed performance level. The fault tolerant controller contains two parts:the state feedback controller and fault compensator. A delay-dependent condition based on linear matrix inequality (LMI) is proposed for fault tolerant controller. The effectiveness of proposed design method is demonstrated by a simulation example.
