摘要
利用最小二乘法辨识原理,推导了电液调节系统辨识用数学模型,并用某电厂300MW国产汽轮机数字电液调节系统的现场试验数据进行了参数辨识仿真。仿真结果表明,采用最小二乘法对汽轮机电液调节系统进行参数辨识,辨识结果基本满足精度要求,效果良好。
This article,by elaborating and analyzing the method of least squares identification principle,has deduced the mathematical model of DEH Regulating system identification.And then based on the field test data of the DEH system of a power plant it conducts the parameter identification and simulation.The results show that in the application of the method of least squares to DEH system parameter identification,identification result can basically satisfy the requirement of accuracy and that parameter identification has obtained good results.
