摘要
根据电路模型单元库实现装备数学模型和物理模型的映射匹配,是基于模型的装备快速测试中的一项关键技术。电路模型匹配技术是进行基于装备物理模型进行故障诊断的基础。对模拟电路中的基本数学模型单元和物理模型单元进行了总结,建立了相应的模型库,针对装备中最基本的单元——可观测的模拟电路系统,提出了利用微分进化算法进行模拟电路模型匹配的方法。对阻抗测量电路的匹配实验结果表明,该方法能实现模型结构的完全匹配,模型参数的匹配误差在1%以内。
The mapping and matching of the system＇s mathematical model and physical model according to circuit model library is one of the key techniques in fast testing of equipments based on models. Matching technique of circuit models is the basis of the fault diagnosis based on physical model. The fundamental mathematical and physical model units of analog circuits are summarized for the model-library, the model matching method for analog circuits is developed based on differential evolution algorithm because of the analog circuits which is the basis unit of the equipments. The experimental results of an impedance measuring circuit show that the model structure can be matched perfectly by this method, and the matching error of model parameters is below than 1%.
