基于键合图的飞跨电容型逆变器故障诊断研究
Fault diagnosis research of flying capacitor inverter based on bond graph
摘要
Abstract
Based on analyzing structure and characteristic of flying capacitor inverter , we diagnose the parametric fault of inverter , and conduct global analytical redundancy relation method based on bond graph model to carry out detec -tion and localization of the parametric fault .The bond graph model of flying capacitor inverter is established according to bond graph theory , through the way of adding observation signal and virtual sensor to bond graph model , the diag-nosis bond graph model of system is established , and thus the global analytical redundancy relation of system is ob-tained.Finally, 20-sim simulation platform is used to conduct simulation and analysis , and it verifies that the global analytical redundancy relationship based on bond graph model is feasible in the aspect of parametric fault diagnosis .关键词
