摘要(Abstract):
根据系统参数辩识原理 ,利用仿真数据 ,采用最小二乘法对调节系统特性参数进行寻优。结果表明采用辩识方法可以准确地辩识系统各时间参数。辩识结果准确可靠 ,可以用于对调节系统进行性能预测、控制优化和故障诊断
The least square method is adopted by searching the optimal parameter of governor according to the principle of system identification. Results indicate that parameter can be identified properly each time. The identifying result is credible. And the method can be used in performance predicating, control optimal and failure diagnosing.
