Synchronization of a class of chaotic systems with both uncertainty and disturbance by the UDE-based control method

In this paper, synchronization of chaotic systems with both uncertainty and disturbance is investigated. Firstly, a new uncertainty and disturbance estimation (UDE)-based control method is proposed, which are composed of two controllers, one is the stabilization controller, the other is the UDE controller. Then, two examples are studied by the above method. Finally, numerical simulations verify the effeteness and correct of the theoretical results.
