Abstract :
In this paper, a methodology for the synchronization of two chaotic systems by means of a sampled driving signal is presented. The method is based on the fuzzy Takagi-Sugeno representation of the chaotic system, from which a continuous-time fuzzy observer is designed as the solution of an LMI problem. Then, via the dual-system, the fuzzy observer is digitally redesigned such that the performance is maintained for the sampled system. Numerical simulations of Chua´s circuit are used to illustrate the effectiveness of the proposed synchronization methodology.
