摘要
根据直流沸腾系统的特点,采用了以集中参数和可移动边界为特征的简化动态模型,推导出了两相流反馈系统。利用自动控制中的频域理论以及MATLAB软件的不稳定性分析语句和Tool Box 中的Simulink工具,对其进行了分析和仿真,并得出了几种主要因素影响下的稳定性边界曲线。
Considering the characteristic of once-through boiling flow system, the simplified dynamic model with lumped parameter moving boundary is used to describe two-phase flow feedback system for instability analysis. The transfer-functions for instability analysis are derived from the frequency-domain analysis method on automatic control. The Matlab software and its Simulink tools are used to analyze and simulate the instability of once-through boiling flow system. Then the stability boundary curves under the effect of some major factors are obtained.
