Adaptive projective synchronization and parameter identification of Takagi-Sugeno fuzzy hyperchaotic systems

The projective synchronization problems of uncertain hyperchaotic systems is investigated. Based on the Takagi-Sugeno （T-S） fuzzy model，an adaptive controller and the parameter update rule are designed. The feasibility of the proposed scheme is verified according to Lyapunov stability theory. Using the designed controller，parameters identification and the projective synchronization of uncertain hyperchaotic systems can be achieved simultaneously. Hyperchaotic Lorenz system is employed to illustrate the effectiveness of the proposed scheme.
