摘要/Abstract

摘要： 针对一类存在有界干扰的线性参数化非线性系统,给出了一种新的适应输出反馈控制器.该控制器能保证闭环控制系统所有信号的全局有界性.该文将现有的非线性适应输出反馈控制方面的结果,从无扰动情形推广到了存在有界干扰的情形.仿真结果用来说明所设计控制器的有效性.

关键词: 线性参数化非线性系统, 适应输出反馈, 全局有界

Abstract: A new adaptive output-feedback controller is proposed for a class of linearly parameterized nonlinear systms with bounded disturbances. The controller can guarantee the global boundness of all closed-loop signals. The results we have obtained extend the existing results in the field of adaptive output-feedback nonlinear control from no disturbance cases to cases with bounded disturbances. The simulations are given to show the effect of the designed controller,

Key words: linearly parameterized nonlinear system, adaptive output-feedback, global boundness
