| 摘 要： | 本文研究有界非匹配不确定性SISO非线性系统的跟踪问题，为克服变结构控制的抖动现象，设计了动念变结构控制方案，得到本质上时间连续的变结构控制律，并且考虑了广系统在有界模型不确定性及外加干扰情况下控制的鲁捧性。最后给出的仿真实例证实了理论结果。

| Abstract: | The problem of output tracking in nonlinear systems with non-matching uncertainties was studied. A method of dynamical variable structure control was proposed to reduce the effect of chattering. The resulting controller output is a continuoues function of time in essential. So the chattering phenomenon is avioded. It is shown that this scheme will yield robust performance against the uncertainties. The results were illustrated by a example. |
