Impulsive synchronization control of fuzzy chaotic systems based on output feedback

A new method of impulsive synchronization control for fuzzy chaotic systems is proposed in the paper by using output feedback. In real systems, all states in the drive system are not available. Comparing with the way of state feedback, the method in the paper is more useful and more realistic. Via Schur complement theorem, linear matrix inequality (LM I) toolbox, stability analysis of Lyapunov functions and variable transformation, the paper estimates the systems states and proves exponentially stable and robust stable conditions, realizes the synchronization control of error systems, and then designs the output feedback control matrix using MATLAB toolbox. Simulation results demonstrated the effectiveness of the proposed method.
