摘要

本文针对一类具有未知乘项的非线性系统,提出了一种多模型自适应控制器。与以往的结果不同,我们不需要未知控制方向的先验知识。我们提出的自适应控制器是一种切换型控制器,它可以通过切换方案重新初始化其估计参数。因此,可以快速识别未知的控制方向,使控制律按正确的方式工作。证明了闭环切换系统的全局渐近稳定性。

Logic-based switching control of a class of nonlinear system
In this note, a multiple model adaptive controller was developed for a class of nonlinear system which has unknown multiplicative terms. Unlike previous results, we do not require a priori knowledge on the unknown control directions. Our proposed adaptive controller is a switching-type controller which can re-initialize its estimate parameters via a switching scheme. Therefore, the unknown control directions can be identified quickly, so that the control law can work on the right way. Global asymptotic stability of the closed-loop switching system is proved.
