摘要
介绍以上海船舶运输科学研究所研制的ＤＹＴ—８８—Ｑ数字控制装置为核心的双抽汽式汽轮机数字电液调节系统及其控制方法。首先简述系统的设计思想、结构，列示与以往调节系统相比的特点，接着介绍ＤＹＴ－８８－Ｑ数字控制装置的控制方法──基于物理模型，应用结合模糊数学方法和专家系统方法的智能控制方法。最后介绍该系统的试验结果及在电厂使用情况。
The numerical electrohydraulic adjust system of double pass-out turbine,of which the key device is the DYT-88-Q numerical control device researched and manafactured by SSSRI,and its features of control method are introduced in the papers. As a most advanced and low cost product of numenical electrohydraulic adjust system of domestic small turbine,it has good spreaded future.
