针对一类非线性系统，提出了一种基于间断函数等效控制方法的滑模观测器。给出了观测器的结构及其存在条件。此外，本文还研究了一类高阶滑动算子的一致（w.r.t.初始条件）有限时间收敛性和减小抖振效应。在观测器设计中使用这些操作员允许计算的等效控制和观测器收敛在有限时间内一致。最后给出了一个仿真例子来说明所提出的方法。
In this paper a sliding-mode observer based on the equivalent control method for discontinuous functions for a class of non-linear systems is proposed. The observer structure and its existence conditions are presented. Besides, a class of high order sliding operators with the properties of uniform (w.r.t. initial conditions) finite time convergence and with reduction of chattering effect are exposed. The use of these operators in the observer design allows the calculation of the equivalent control and the observer convergence uniformly in finite time. A simulation example is presented to illustrate the proposed method.
