摘要:

本文提出了一种动态反步方法,用于设计纯反馈非线性系统的控制器,传统反步方法在求解隐式非线性代数方程时存在困难。该方法的核心思想是在每次递归步骤中将(虚拟)控制作为状态。随着新动态的引入,所设计的控制器具有动态反馈形式。详细阐述了控制器的设计过程,并在每个步骤中执行一次额外的Lyapunov设计。在适当假设下,所提出的控制方案实现了统一渐近稳定性。通过稳定化和跟踪的数值示例展示了该方法的有效性。

英文摘要:

A dynamic backstepping method is proposed to design controllers for nonlinear systems in the pure-feedback form, for which the traditional backstepping method suffers from solving the implicit nonlinear algebraic equation. The idea of this method is to augment the (virtual) controls as states during each recursive step. As new dynamics are included in the design, the resulting controller is in the dynamic feedback form. Procedure of deriving the controller is detailed, and one more Lyapunov design is executed in each step compared with the traditional backstepping method. Under appropriate assumptions, the proposed control scheme achieves the uniformly asymptotically stability. The effectiveness of this method is illustrated by the stabilization and tracking numerical examples.
