摘　　要：本文着眼于闭环环境下动态系统中的故障诊断问题.介绍了目前闭环系统故障诊断的研究意义,特别关注了开闭环故障诊断的不同,并概述了现有的闭环系统故障诊断方法.通过仿真实验比较了典型开环系统和闭环系统中故障诊断的不同性能.最后探讨了闭环系统故障诊断研究中亟待解决的问题以及未来可能的研究方向.Fault diagnosis for closed-loop systems is reviewed in this paper. The research background of fault diagnosis problem for closed-loop systems is introduced, and special attentions are paid to the study on the differences between fault diagnosis for open-loop systems and closed-loop systems. Existing fault diagnosis methods for closed-loop systems are also summarized. Some simulation examples are employed to illustrate the different fault diagnosis performances between typical open-loop systems and closed-loop systems. Finally, some challenging problems and promising research directions are nointed out.
