Synchronizing chaotic systems using backstepping design. (English) Zbl 1035.34025

The paper deals with the problem of synchronization of coupled systems. Given two systems (possibly exhibiting chaotic dynamics) \(x'=f(x,t)\) and \(y'=f(y,t)+u\), \(x,y\in \mathbb{R}^{n}\). The authors propose a recursive procedure for designing an appropriate control \(u\), which makes the systems synchronized, i.e., \(\| x(t)-y(t)\| \to 0\) as \(t\to\infty\), for some set of initial conditions. The algorithm combines the choice of the Lyapunov function with the design of a controller.
