讲座简介：

In this talk, a new extended sliding mode observer for a class of second-order linear systems is discussed. It will be shown that, when the sampling period is small enough, the unmeasurable state estimation errors can be numerically approximated by using the measurable system output information and then used for constructing the switching functions of the sliding mode observer, to drive the observer error dynamics to reach and then slide across the sliding surfaces. The advantages of the proposed new extended sliding observer are in then following three points: (i) It has a solid theoretical background of stability and convergence ; (ii) The designed new observer can sufficiently approximate the observer-like system when the sampling period is small enough; (iii) The achieved fast error convergence is very helpful for practical implementations.
