摘要
介绍了ＣＴＥＳ—１控制技术实验系统中有关系统建模方面的内容。在该系统中包括有两种建模方法：阶跃响应法和相关分析辨识法．传统的阶跃响应法具有简便、直观、建模速度快等优点，当机组运行条件允许进行阶跃实验时，这种方法有很大的实用价值。相关分析辨识法克服随机干扰能力较强，对运行过程的干扰小，能得到较精确的数学模型。
This paper discribes two modeling methods of CTES-1 control technique experimentsystem: real field method (RFM) and relation analysis method (RAM). RFM has advantagesof fast speed modeling and strong ability of overcoming disturbance. RFM is very usefulwhen turbo-unit and boiler run unstablely. In stable running condition,RAM has advantages of high precision mode and strongly overcoming radom-disturbance ability..CTES-1 had been authenticated by engineering specialists in the province-grade assessment meeting heldin Jan 12 1993.
