本文介绍了带调压室的弗朗西斯涡轮机的动态建模和水电站的控制。非线性和线性模型包括技术参数，并显示出与测量数据高度相似。基于涡轮机模糊模型，提出了一种基于内模控制的涡轮机功率控制方法。考虑到在涡轮机功率的整个区域中的适当的控制响应，从模糊模型确定过程的模型参数，该模型参数进一步包括在内模控制器中。的结果进行了比较，比例积分（PI）控制器调整与积分绝对误差（IAE）的目标函数，并显示了改进的响应内模控制。
This paper presents dynamic modelling of a Francis turbine with a surge tank and the control of a hydro power plant (HPP). Non-linear and linear models include technical parameters and show high similarity to measurement data. Turbine power control with an internal model control (IMC) is proposed, based on a turbine fuzzy model. Considering appropriate control responses in the entire area of turbine power, the model parameters of the process are determined from a fuzzy model, which are further included in the internal model controller. The results are compared to a proportional-integral (PI) controller tuned with an integral absolute error (IAE) objective function, and show an improved response of internal model control.
