本文研究了线性切换系统的集转移可观性问题。集合转换（ST）可观测性问题考虑当模式集合被划分为两类时，对应于例如操作的安全模式（SM）和操作的故障模式（FM），如本文所研究的。ST可观测性问题是在系统处于安全工作模式的情况下，从系统的输出中识别出从安全到故障的模式序列转换。研究了具有自治线性时不变（LTI）子系统动态且无状态跳变的切换系统的ST能观性问题。在安全操作模式中开始反映了许多系统监控应用，其中系统由技术人员初始化或重置。应用包括中风和心脏病发作检测和组件故障。本文的主要贡献是给出了具有LTI子系统的切换系统ST能观的充分必要条件。
In this paper, we develop and investigate the set transition observability problem for switched linear systems. The set transition (ST) observability problem considers when the set of modes is partitioned into two classes, corresponding for example to safe modes (SM) of operation and failure modes (FM) of operation, as studied herein. The ST observability problem is to identify mode sequence transitions that move from safe to fail from the output of the system given that the system initializes in a safe operating mode. We address the ST observability problem for switched systems with autonomous linear time-invariant (LTI) subsystem dynamics and no state jumps. Beginning in a safe operating mode reflects many system monitoring applications where the system is initialized by a technician or a reset. Applications include stroke and heart attack detection and component failures. The main contribution of this paper is a necessary and sufficient condition for ST observability of switched systems with LTI subsystems.
