Research on fuzzy control for steam generator water level

In order to overcome shortcomings of the traditional PID controller for nuclear steam generator water level, we proposed a fuzzy controller by using fuzzy reasoning. By summing up the experience of skilled operators, we gave a set of fuzzy control rules, and determined some important control parameters. To verify the effectiveness of fuzzy controller, a simulation for a steam generator in Qinshan nuclear power plant, for example, was given. Simulation results show that the method can effectively improve the control quality.
