摘　　要：在设计变结构控制器的过程中，确定对象不确定性的范围是一个重要的前提步聚。但是，在某些情况下要确定其边界是相当困难的，或者存在不能精确描述的外部扰动不可能得到其变化的准确范围。针对上述问题，在传统的变结构控制器中加入了对应不确定因素的自适应环节，并证明了该方法设计之控制器的稳定性。仿真结果表明了该法的有效性。During desier proces of variable stucture controller, detemination of bounds ofuncertainties of the object is a very important premise.Bus, in some cases, determination ofthe bounds is rather difficult, or there are some outer disturbance that are not able to be pre-cisely described by math method so that it is impossible to get their exact bounds. Aimed of theabove - mentioned, problem an adaptive loop corresponding to the uncertain factors is added tothe traditional variable structure controller in this paper. the stability of such controller hasbeen erified.Simulation results show that this mehod is effective.
