Abstract: Chaos theory is a research field, which studies the behavior of nonlinear dynamical systems that are highly sensitive to initial conditions, an effect which is popularly called as the butterfly effect. Synchronization of chaotic systems is a phenomenon that may occur when two, or more, chaotic oscillators are coupled, or when a chaotic oscillator drives another chaotic oscillator. Because of the butterfly effect which causes the exponential divergence of the trajectories of two identical chaotic systems started with nearly the same initial conditions, synchronizing two chaotic systems is seemingly a very challenging problem. In most of the chaos synchronization approaches, the master-slave or drive-response for- newlinemalism is used. If a particular chaotic system is called the master or drive system and another chaotic system is called the slave or response system, then the idea of the synchronization is to use the output of the master system to control the slave system so that the output of the slave system tracks the output of the master system asymptotically. Hyperchaotic systems have more complex dynamic behavior than chaotic systems. Hyper- chaotic system is defined as a chaotic system with at least two positive Lyapunov exponents, implying that its dynamics can be expanded in several directions simultaneously. The first part of this dissertation investigates the global chaos synchronization of chaotic systems using the nonlinear control and backstepping control methods. The nonlinear controller design can be divided into two steps: the first step involves the derivation of control Lyapunov function and the second step involves using existing control Lyapunov function to synchronize the chaotic and hyperchaotic systems. The theorems on global chaos synchronization are established using Lyapunov stability theory. The first part of the dissertation also investigates the backstepping control design with re- cursive feedback for controlling chaotic systems to guarantee the complete synchronization of chaotic systems.
