滑动模式观测器具有独特的性质，因为能够在测量的工厂输出和观测器的输出之间的误差上产生滑动运动，确保滑动模式观测器产生一组与工厂的实际输出精确相称的状态估计。同样的情况是，对所应用的观测器注入信号（所谓的等效注入信号）的平均值的分析包含关于用于定义观测器的模型与实际设备之间的失配的有用信息。这些独特的属性，再加上这样的事实，即不连续的注入信号，这被认为是有问题的许多控制应用没有缺点的基于软件的观测器框架，产生了感兴趣的滑模观测器方法在最近几年的地面膨胀。本文介绍了线性和非线性滑模观测器范例的概述。使用的等效注入信号的故障检测和状态监测有关的问题进行了演示。还描述了一些应用特定的结果。在该领域的文献中提出和合格的范围内不断发展的理论和滑模观测器的应用的广泛领域。
Sliding mode observers have unique properties, in that the ability to generate a sliding motion on the error between the measured plant output and the output of the observer ensures that a sliding mode observer produces a set of state estimates that are precisely commensurate with the actual output of the plant. It is also the case that analysis of the average value of the applied observer injection signal, the so-called equivalent injection signal, contains useful information about the mismatch between the model used to define the observer and the actual plant. These unique properties, coupled with the fact that the discontinuous injection signals which were perceived as problematic for many control applications have no disadvantages for software-based observer frameworks, have generated a ground swell of interest in sliding mode observer methods in recent years. This article presents an overview of both linear and non-linear sliding mode observer paradigms. The use of the equivalent injection signal in problems relating to fault detection and condition monitoring is demonstrated. A number of application specific results are also described. The literature in the area is presented and qualified in the context of continuing developments in the broad areas of the theory and application of sliding mode observers.
