摘要
本文针对极点配置法扩张状态观测器ESO的不足,充分利用系统已知信息设计出一种新型ESO,并将其与变结构控制理论相结合,提出一种非线性鲁棒变结构控制器的设计方法,克服了基于反馈线性化理论的非线性控制因数学模型的误差而影响控制器性能的缺点。仿真结果表明所设计的非线性鲁棒变结构控制器对于对象模型参数摄动和外扰具有良好的适应性和鲁棒性。
In order to overcome the shortcoming of the pole-configuration-method extended state observer(ESO),a new model of ESO,based on using known information of detected system,is put forward in this paper.And a new controller of nonlinear robust variable structure controller(NLRVSC) is put forward by cooperating variable structure control(VSC) theory with ESO to overcome the shortcoming of feedback linearization excitation controller,which performance is affected by the mathematical model error.The simulation res...
