| Research Abstract |
In this study, we developed the model based diagnosis technique for a rotational shaft, an engine mount and an air-conditioner. First, we build models by using Modelica language. And then, we build various abnormalities in a model. Modeling was carried out by Physical relations both for normal and abnormal phenomenon. Second, simulations were done with and without failures to develop diagnosis technique. We used semantic network, inverse technique and support vector machine for diagnosis. Finally, we confirmed our developed technique well distinguished an abnormal case from normal one.
