水轮机参数在线辨识及调节器参数自整定

ON LINE IDENTIFICATION AND ADAPTIVE PID GOVERNOR OF HYDRAULIC TURBINE

本文以一般混流式水轮机的六参数模型为基础 ,推导了参数在线辨识的算法 ,研究了 PID调节器参数在线整定的方法 ,利用仿真技术对整套方案的实现进行了仿真 ,并对此自适应控制方案的性能进行了分析。

Basing on the hydraulic turbine 6 parameter model,the algorithm of the parameters identification is derived and the PID adaptive governor is obtained.Additionally,by using the computer simulation techniques,the regulating property of the adaptive governor is presented,and is compared with that of the classic governor.
