Uncertain master–slave synchronization with implicit minimum saturation level

In this note, the exponential synchronization of a class of chaotic uncertain systems is addressed. A linear state feedback control is used which guarantees the synchronization when uncertainties are present both in linear and nonlinear parts of the slave system dynamic. It is shown that, with some a-priori rough bounds on the slave uncertainties, the closed loop stability can be guaranteed. Numerical simulations are presented to show the effectiveness of the proposed method.
