Projection Synchronization of a Class of Complex Chaotic Systems with Both Uncertainty and Disturbance

Abstract EN

This paper mainly investigates the projection synchronization of complex chaotic systems with both uncertainty and disturbance.

Using the linear feedback method and the uncertainty and disturbance estimation- (UDE-) based control method, the projection synchronization of such systems is realized by two steps.

In the first step, a linear feedback controller is designed to control the nominal complex chaotic systems to achieve projection synchronization.

An UDE-based controller is proposed to estimate the whole of uncertainty and disturbance in the second step.

Finally, numerical simulations verify the feasibility and effectiveness of the control method.
