动态系统基于模型诊断的研究进展与展望

Research Development and Prospect of Model-based Diagnosis of Dynamic Systems

基于模型诊断是为了克服传统故障诊断方法的缺点而兴起的一项新型的智能推理技术,其应用也越来越广泛。介绍了动态系统基于模型诊断的诊断过程,综述了建模诊断方法、时序基于模型诊断方法。通过与静态诊断的比较,指出动态系统基于模型诊断的各种定义及其研究意义,并指出有待解决的问题。

Model-based diagnosis (MBD) is a new type of intelligent reasoning technology, overcoming tradition-al fault-diagnosis methods' shortcoming,and more and more widely applied.The process of MBD of dynamic sys-tems is introduced, the methods of modeling and diagnosis,and temporal MBD are summarized. By comparingwith static diagnosis, several definitions of dynamic diagnosis are presented and their research significance is re-vealed.The open problems of MBD of dynamic systems are also pointed out.
