| 中文摘要 |
| 讨论了凸胞型不确定系统的变结构控制, 利用LMI方法, 给出了滑模面存在的充分条件, 并且给出了线性滑模面的显式表达式. 所设计的变结构控制律不仅能保证系统在有限时间到达滑模面, 并且保证受限在滑模面上的降阶等价系统是DR稳定的. 最后, 给出一个设计实例来阐明该控制方法的有效性. |
| 英文摘要 |
| The problem of designing a variable structure control law for uncertain polytopic systems is considered in this paper. Firstly, a sufficient condition for the existence of linear sliding surfaces in terms of linear matrix inequality (LMI) is given, an explicit formula of linear sliding surfaces is also presented. Secondly, variable structure control law is designed, which not only guarantees the system to reach the sliding surface in finite time, but also assures the DR stability of the reduced-order equivalent system on the sliding surface. Finally, an example is presented to show the efficiency of this control law. |
