This paper studies the transmission synchronization (TS) problem among multiple coupled chaotic systems by considering unknown parameters. In the solving process, we firstly select a special integral sliding surfaces, and then we develop an effective controller with the compensation terms to guarantee the asymptotical stability of all TS error systems. Simultaneously, we design the proper adaptive...
In this paper, finite-time synchronization (FTS) problems in an array of unified chaotic and hyperchaotic systems are mainly studied using some important control methods. First, FTS and finite-time transmission synchronization (FTTS) for N systems are realized in a finite time by designing the effective control schemes, and the stability criteria can be given. The corresponding examples are presented...
This paper addresses a problem of chaotic secure communication. Unlike existing works, the switched chaotic system with three sub-chaotic systems is employed for providing high-security in communication. To end this, not only the appropriate synchronization scheme but also an adaptive estimator for estimating switching signals are designed. From simulation results, it can be found that proposed methods...
This paper considers the guaranteed cost synchronization problem for a class of chaotic systems. Using a convex representation of error dynamics, state and output feedback LPV (Linear Parameter Varying) controllers are proposed. The criteria for the existence of the controllers are derived in terms of LMI (Linear Matrix Inequality). Numerical examples show the effectiveness of the proposed method.
