| 摘 要： | 对变结构控制设计中的离散趋近律方法进行深入研究,提出了"理想趋近律"与"鲁棒趋近律"的概念.基于这些概念可以将离散趋近律区分为两类.研究了采用不同类型趋近律求取变结构控制时的异同及鲁棒性保证机理.澄清了使用趋近律方法设计变结构控制时存在的混乱和误解.

| Abstract: | The reaching-law approach,which is widely used in designing the discrete-time variable-structure controller, is thoroughly studied in this paper.Based on the new concepts of the"Ideal Reaching Law"and the"Robust Reaching Law"proposed here,we classify the reaching-laws into two types.The mechanisms of robust controller designed based on these two types of reaching-laws are different.The similarities and differences are analyzed so that the confusion and misapprehension on reaching-law approach can be clarified. |

| Keywords: | discrete-time systems variable structure control reaching law robustness |
