摘要

基于非线性鲁棒控制理论，针对一类单输入单输出连续搅拌反应釜（CSTR）模型设计了具有高增益观测器的非线性鲁棒控制器（ONRC），并提出了一种简单的控制器参数整定方法。与非线性鲁棒控制器（NRC）和滑模控制方法（SMC）的仿真结果比较表明，ONRC对系统不确定性和干扰具有更好的抑制作用，通过Monte-Carlo试验检验显示，ONRC在模型参数摄动时具有更好的性能鲁棒性。

Abstract

This article considers the design of nonlinear robust controller with high gain observer (ONRC) for single-input/ single-output system of continuous stirred-tank reactor (CSTR) based on a nonlinear robust theory.To facilitate its implementation

a simple parameter tuning method was suggested.Through comparison of simulations with NRC and sliding model controller (SMC)

it was found that the proposed schemes ONRC appeared to restrain the system uncertainties and disturbances better.Monte-Carlo experiments also suggested the better robustness of ONRC.
