一类非线性系统的高增益输出反馈控制(英文)

High-Gain Output Feedback Control for a Class of Nonlinear Systems

对一类具有非稳定化的线性部分和未知扰动非线性系统进行高增益输出反馈控制设计.首先通过一个线性状态变换,将原系统变为一个线性部分可稳定化的新系统;其次,对观测器和控制器进行设计.控制器保证了闭环系统平衡态的全局渐进稳定.

A high-gain observer control design is considered for a class of nonlinear systems with unstabilizable linear part and unknown disturbances.By a linear state transformation,the original system is transformed into a system with stabilizable linear part.A controller accompanied by an observer is constructed.The controller guarantees the globally asymptotic stability of the origin of the closed-loop system.
