This article proposes a virtual sensor for piecewise linear systems based on observability analysis that is in function of a commutation law related with the system's outpu. This virtual sensor is also known as a state estimator. Besides, it presents a detector of active mode when the commutation sequences of each linear subsystem are arbitrary and unknown. For the previous, this article proposes a set of virtual estimators that discern the commutation paths of the system and allow estimating their output. In this work a methodology in order to test the observability for piecewise linear systems with discrete time is proposed. An academic example is presented to show the obtained results.
本文提出了一种基于观测分析的分段线性系统虚拟传感器，其功能与与系统输出相关的换路规律有关。这种虚拟传感器也被称为状态估计器。此外，当每个线性子系统的换路序列是任意和未知时，它还提出了一种主动模式检测器。对于前者，本文提出了一组虚拟估计器，用于辨别系统的换路路径，并允许估计它们的输出。在这项工作中，提出了一种用于测试具有离散时间的分段线性系统可观测性的方法。本文给出了一个学术示例来说明所得到的结果。
