According to the inherent characteristics of hydroelectric generating set and the problems existing in the process of speed regulation, a generalized self-tuning speed regulation method with pole configuration is proposed. Including the establishment of the controllable autoregressive moving average (CARMA) model of hydro-generating units, the on-line identification method of model parameters and the pole placement method of control system are given. The adaptive speed control method can effectively overcome the system time-varying, nonlinear and interference on the control performance, simulation studies show that under the control of this method, the dynamic performance and robustness of hydro-turbine speed control system Have been significantly improved
