초록

This paper presents analysis of linear model boiler-turbie system model of Bell and Astrom. The 3rd order nonlinear model is linearlized and the linearized models of several operating points are presented. The analysis results show that the linearlized model is relatively reliable except the dynamics of electric output and drum level. Therefore, a caution is necessary in controller design based on the linearlized model.
