This paper addresses the problem of the synchronization of a class of chaotic oscillators using techniques borrowed from a recently proposed control design based on Takagi-Sugeno (TS) fuzzy modeling. In order to attain better synchronization, this TS fuzzy modeling is combined with the robust H∞ observer theory based on linear matrix inequalities. A laboratory setup based on Chua's oscillator circuit is used to demonstrate the main ideas of the paper. Information transmission experiments are performed as an index to measure the effectiveness of the proposed approach.
