报告摘要：As the size and complexity of practical systems continue to grow, significant attention has been paid to the problems of fault diagnosis and fault tolerance in large-scale dynamical systems. The solutions to these problems are crucial and necessary for many life-critical applications. This talk will present several approaches to address these problems under the framework of discrete event dynamic systems (DEDS). The first part of this talk will focus on fault diagnosis approaches that are based on finite-state machine (FSM) models with unreliable sensor observations. The second part of this talk will focus on fault tolerance approaches that are based on Petri net (PN) models. In particular, techniques on state/event estimation, fault-tolerant design, and controller optimization will be introduced, which are able to provide fault tolerance capabilities to existing systems (controllers) while retaining their original operating objectives.
