摘要
本文介绍了几种基于数学模型的故障检测与分离技术;着重阐述了基于系统线性时不变离散状态方程的故障检测与分离过程;评介了故障可分离性、敏感性、鲁棒性等衡量故障检测质量的性能指标。在本文的最后,讨论了故障检测与分离技术的前沿性研究课题。
In this paper, several kinds of FDI methodologies based on plant models have been surveyed, and emphasises have been laid on the statement of FDI procedure using plant＇s linear time-invariant discrete state equations. Performance indexes, such as, isolability, sensitivity and robustness which evaluate the effectiveness of FDI, have been introduced and commented on. Finally,the frontier of FDI have been pointed out.
