Abstract

In this paper, in order to realize the predefined-time control of n-dimensional chaotic systems with disturbance and uncertainty, a disturbance observer and sliding mode control method were presented. A sliding manifold was designed for ensuring that when the error system runs on it, the tracking error was stable within a predefined time. A sliding mode controller was developed which enabled the dynamical system to reach the sliding surface within a predefined time. The total expected convergence time can be acquired through presetting two predefined-time parameters. The results demonstrated the feasibility of the proposed control method.

基于扰动观测器的混沌系统预定义时间滑模控制。
本文提出了一种扰动观测器和滑模控制方法,以实现具有扰动和不确定性的 n 维混沌系统的预定义时间控制。设计了一个滑动流形,以确保误差系统在其上运行时,跟踪误差在预定时间内保持稳定。还开发了一种滑动模式控制器,使动力系统能在预定时间内到达滑动面。通过预设两个预定义时间参数,可以获得总的预期收敛时间。结果证明了所提出的控制方法的可行性。
