Abstract

This paper presents a systematic design methodology for fuzzy observer-based secure communications of chaotic systems with guaranteed robust performance. The Takagi-Sugeno fuzzy models are given to exactly represent chaotic systems. Then, the general fuzzy model of many well-known chaotic systems is constructed with only one premise variable in fuzzy rules and the same premise variable in the system output, Based on this general model, the fuzzyobserver of chaotic system is straightforwardly given and leads the stability condition to a linear-matrix inequality (LMI) problem. When taking the fuzzy observer-based design to applications on secure communications, the robust performance is presented by simultaneously considering the effects ofparameter mismatch and external disturbances. Then, the error of the recovered message is stated in an H-infinity criterion. In addition, if the communication system is free of external disturbances, the asymptotical recovering of the message is obtained in the same framework, The main results alsohold for applications on chaotic synchronization Numerical simulations illustrate that this proposed scheme yields robust performance.
