Modelling and internal fuzzy model power control of a Francis water turbineNagode, Klemen (Avtor) Škrjanc, Igor (Avtor) Francis turbinefuzzy controlfuzzy modelinternal model controlhydro power plantsThis 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.20142021-08-30 16:14:37Članek v reviji129235UDK: 681.5.015:621.224.24ISSN pri članku: 1996-1073DOI: 10.3390/en7020874COBISS_ID: 10430292sl
