| 中文摘要 |
| 本文针对线性多变量不确定性系统，提出了变结构逻辑极值控制律形式及其设计方法．该控制律完全基于被控对象的标称模型和不确定性因素上下界，建立起了不确定性因素变化范围与控制律参数逻辑之间具有一般性的关系．无论不确定性因素是否满足匹配条件，均能保证变结构控制系统的滑动模态存在 |
| 英文摘要 |
| In this paper，a new variable structure control law that is called logic and extreme control law is proposed for multivariable linear plants with matched or mismatched uncertainties. Its designing method，which is totally based on the plant nominal models and the uncertainties' extreme values，is also studied.Meanwhile，some direct and general relations between the uncertainties' variation ranges and the control laws' parameters are established. No matter what concrete forms the uncertainties have，the control law designed here ensures that the sliding mode exists. The control law got in this paper is suited to many areas, and is easy to realize in engineering. |
