摘要
根据水轮发电机组的固有特性和调速过程控制中存在的问题 ,提出了一种具有极点配置的广义自校正调速方法。其中包括建立了水轮发电机组的可控自回归滑动平均(CARMA)模型 ,给出了模型参数的在线辩识方法和控制系统的极点配置方法。这种自适应调速方法能够有效地克服系统时变、非线性及干扰对控制性能的影响 ,仿真研究表明在这种控制方法作用下 。
A CARMA model of the hydroelectric generating unit is established by analyzing its performance. Then a self\|adaptive governing method with pole location is presented in consideration of the intrinsic characteristic of a hydroelectric generating units and the problem with the governing control. Online identification of the model parameter and suitable pole location are contained in it. Influences of the time varying parameters and the disturbances on control behavior of the system are eliminated by the use of the self\|adaptive control method. The transient and robust performances of the governing system are improved obviously.
