Research on system monitoring, fault detection, and fault isolation is extremely important for guaranteeing reliability, safety, integrity, and efficiency of plants, technical processes, and especially safety-critical systems. In this paper we first discuss, analyze, and compare two known centralized observer-based fault isolation schemes. Secondly we devise and discuss their distributed implementations. We finally evaluate and compare the potentialities of the different fault isolation schemes and their distributed implementations considering a benchmark case study.

基于模型的故障隔离和持久故障隔离：集中和分布式实现

系统监控、故障检测和故障隔离的研究对于保证工厂、技术流程，尤其是安全关键系统的可靠性、安全性、完整性和效率极为重要。在本文中，我们首先讨论、分析和比较两种已知的基于集中观察器的故障隔离方案。其次，我们设计并讨论了它们的分布式实现。我们最终评估和比较了不同故障隔离方案及其分布式实现的潜力，并考虑了基准案例研究。
