The control effect by using the conventional method is not satisfied because of the grey character caused from time‐variant parameters of hydro‐generator units and its governor. The grey extra‐deleting control theory is applied to the governor design of hydro‐generator units in this paper. After the mathematic model of hydro‐generator and its governor are founded, the grey extra‐deleting controller is designed and its effect is studied compared with the conventional proportional–integral–derivative governor. The simulation results indicate that the grey extra‐deleting controller can improve dynamic characteristic of hydro‐generator units.
