This paper investigates the synchronization design for a class of chaotic systems with uncertainties in which all state variables are not measured. The design makes use of an observer with a controller. Assuming the boundedness of chaotic attractors and limited cycles, the approach, which is both global and not relying on complete knowledge of the systems involved, is rigorously proved by means of Lyapunov theory. Computer simulation results illustrate the validity of the method.
