| 通过建立基于刚性水击的水电站小波动及水力干扰过渡过程非线性数学模型，从非线性微分几何控制理论出发，提出了构造调节输出函数的设计原则，使得非线性非最小相位系统能完全精确线性化，从而避免了判别零动态稳定性问题。运用该设计原则，推导出水电站小波动及水力干扰过渡过程非线性控制律，同时进行了数值仿真试验。结果表明：本文所提出的非线性控制律计算结果合理，且明显优于常规控制律。 |

mer for the transient process of small disturbance and hydraulic interference in hydropower station，a design principle of output regulation function is suggested according to the nonlinear differential geometric control theory. The design principle can accurately linearize the non-minimum phase systems to avoid the stability problem of zero-dynamics. According to the design principle，nonlinear control strategies of transient process in hydropower station are suggested，and the numerical simulations for a typical hydropower station are carried out. The results indicate that the performance of the suggested control strategies are much better than the conventional control laws and verify that the suggested design principle is correct and applicable. |
