复合系统智能诊断方法研究

随着电子设备系统的日益复杂化,依靠单一的推理技术的故障系统已难以满足复杂系统的诊断要求.将多种不同的推理技术结合起来的集成诊断系统,能够充分利用各自的优点,从而提高系统诊断的正确性和效率,是目前智能诊断研究的一个发展趋势.本文将研究复合系统的智能诊断问题,提出在一个复合系统的诊断过程中,运用基于规则的诊断和基于模型的诊断,两种诊断技术相结合将在诊断的不同阶段发挥出各自的作用,从而建立一个融合了RBD和MBD技术优点的、具有一定学习能力的智能诊断系统.

Research on Intelligent Diagnosis for Composite System

With the gradual complication of some electronic system,using a single reasoning technology is more and more difficult to meet the demand of the fault diagnosis.Combining two or more reasoning technique is a trend of de- velopment of intelligent diagnosis,which can make use of their advantages and improve its efficiency.In this paper we discuss the intelligent diagnosis problem,propose a diagnosis architecture for the composite system,which combines rule-based diagnosis with model-based diagnosis.These two ...
