本文引入了虚拟测试和虚拟诊断的思想,并分别给出了集中控制方式与分布控制方式下可诊断性的判定条件。本文还提供了一种可诊断系统的最优设计。所得结果表明,虚拟诊断比t-故障诊断在同样的系统拓扑结构下能识别更多的故障子系统。
In this paper, the concepts of virtual test and virtual diagnosis are introduced, and the judgment conditions of diagnostability under centralized control and distributed control are respectively given. This article also provides an optimal design of a diagnosable system. The results show that virtual diagnosis can identify more faulty subsystems than t-fault diagnosis under the same system topology.
