Abstract

The objective of this paper is to compare the performance between the anti-windup technique and the saturation degree coefficient skill for the input saturation problem. In this paper, two kinds of saturation adaptive control methods, which are saturation coefficient method and auxiliary system method, are proposed for the arneodo chaotic system with uncertain parameters and input saturation. The stability of closed-loop system under both control strategies is analyzed by using lyapunov theory. Then the comparison is made, and the result shows that both mthods have outstanding performance. But the scheme based on the saturation degree coefficient skill has better performance than the other scheme in terms of the root-mean-square of the tracking error and the root-mean-square of the control energy.
