The generalized projective synchronization of Chua chaotic system is investigated. A new fuzzy observer is designed based on the Takagi-Sugeno (T-S) fuzzy model. According to the Lyapunov stability theory, it is verified that the proposed scheme is feasible and globally stable. Numerical simulations further demonstrate that the projective synchronization of Chua circuit can be achieved by using the proposed scheme. The designed procedure is simple, and the method can be adapted to other chaotic systems.
