摘要
为了妥善解决汽轮机转子热应力数学模型的精度与实时性之间的矛盾,文中由热弹性控制方程出发,运用传递函数、主导极点等控制理论概念建立了一种适宜在线监控应用的汽机转子热应力新模型。仿真结果表明新模型较好地解决了精度与实时性之间的矛盾。
Based on concepts of cybernetics such as transfer functions anddominant roots, a new mathematical model of thermal stresses is developed forsteam turbine rotors, which aims at monitoring and controlling. Digital simulation shows the new mathematical model can meet the requirements both of accuracy and on-line ability.
