摘要
为克服复杂系统定量模型诊断过程中存在的计算复杂、实时性和鲁棒性不强等缺陷,提出了基于定性符号有向图模型的故障诊断方法。研究了定性符号有向图模型的建模机理和诊断推理方法,并将研究成果应用于某电路图进行实例分析。结果表明,该方法诊断快速,建模方便,可以有效地提高复杂系统的诊断能力。
A qualitative symbol digraph Model for complex systems is proposed to avoid the computational complexity,poor robustness,and bad real-time ability of the quantitative model-based methods,which includes the qualitative symbol digraph modeling and reasoning method. Test analysis of a circuit shows that it is convenient to modeling, and diagnoses quickly,and improves the diagnosis ability of complex systems effectively.
