Analysis of Water Level Control Methodsfor Nuclear Steam Generator

    Graphical Abstract
    • Abstract
  • Nuclear steam generator(SG) is a highly complex nonlinear time-changed (system). The inverse dynamics effects, which are caused by shrink and swell under transient, startup and lower power operation, make the water level difficult to control. Methods of SG water level control are analyzed in the paper. The shortcoming of conventional PI(D) control for SG level is pointed out. It emphatically expounds the fuzzy logic control and the neural network control to nuclear steam generator level. Finally, the author brings forward his opinion upon the advance tendency of SG water level control.
