| 摘 要： | 基于非线性微分几何控制理论，给出了针对具有刚性水锤效应的水轮发电机组的非线性调速器控制规律。数字仿真实验表明，这种控制规律能够很好地解决刚性水击的控制问题，与弹性水击的比较表明，在弹性时间常数比较小时，这种控制规律也能够获得满意的控制效果。

| Abstract: | Hydroturbine governor is a very complex nonlinear system and its conventional design methods are PI. PID andderived correction control. so it is difficult to adapt to the change of operational condition. Based on the nonlinear geometriccontrol theory, this paper presents the nonlinear control strategy of hydroturbine governor concerning the rigid waterhammer. A nonlinear mathematical model is set up. The digital simulations demonstrate that the new control 1aw is effectivefor enhancing the stability under large disturbance. The further experiments show that the control strategy derived from therigid water hammer model can also be applied to the system in which the elasticity is not strong. |
