Uncertain Unified Chaotic Systems Control with Input Nonlinearity via Sliding Mode Control

الملخص EN

This paper studies the stabilization problem for a class of unified chaotic systems subject to uncertainties and input nonlinearity.

Based on the sliding mode control theory, we present a new method for the sliding mode controller design and the control law algorithm for such systems.

In order to achieve the goal of stabilization unified chaotic systems, the presented controller can make the movement starting from any point in the state space reach the sliding mode in limited time and asymptotically reach the origin along the switching surface.

Compared with the existing literature, the controller designed in this paper has many advantages, such as small chattering, good stability, and less conservative.

The analysis of the motion equation and the simulation results all demonstrate that the method is effective.
