过程变化检测机理及其应用

CHANGE DETECTION AND ITS APPLICATION FOR PROCESSES

变化检测是检测、分析和分离对象或系统在运行过程中发生的各种变化，以及涉及变化发生的时间、地点、表现形式、作用方式、影响大小等相关问题的一门新兴学科．本文从过程变化的模型描述、检测与诊断技术及其应用开发等几个方面系统地综述了该学科最新的发展状况，探讨了在航天测控工程中潜在的应用价值和具体的实现方法．

Change detection is a new intersecting course to detect and to isolate all kinds of changes appearing in the process of a system. An overview is given on recent development of change modeling, detection, isolation and its application. At the end of this paper, we also discuss the possibility and concrete approaches using change detection methods to deal with monitoring and fault detection in space flight engineering.
