摘要
为提高水轮机调速系统的控制品质 ,根据自抗扰控制 (ADRC)原理 ,针对考虑弹性水击效应的水轮发电机组水门调节的非线性模型 ,对 ADRC的设计进行了改进。基于三相短路故障、负荷扰动和参数变化的数字仿真实验显示 ,改进的 ADRC与微分几何方法的控制性能相当。结果表明扩张状态观测器的扰动观测和补偿作用使得
An improved auto disturbance rejection control (ADRC) controller was designed to control a hydroturbine generator set using the elastic water hammer nonlinear model. Numerical simulations of a threephase short circuit fault, load disturbances and parameter perturbations demonstrated that the performance of the improved ADRC is similar to that of the nonlinear differential geometry control method. ADRC is more adaptable and robust against model uncertainties and disturbances because ESO compensates for all sorts of realtime disturbances.
