Aiming at the time?varying characteristics of hydro?turbine, hydro?turbine model reference adaptive con?trol, which is employed in hydro?turbine regulation system, is researched in this paper. Then the control of hydro?turbine of pumped storage power station based on PID control is put forward. And the mathematical model of hydro?turbine regulation system is established. Combined with Lyapunov stability theory and Popov super stability theory, the change rules of controller parameters have been deduced. The simulation results show that adaptive control per?forms better in adaptability, stability, overshoot and regulation time than PID control.
