Abstract: | A pressurizer is one of important equipment in a pressurized water reactor plant. It is used to maintain the pressure of primary
coolant within allowed range because the sharp change of coolant pressure affects the security of reactor, therefor, the study
of pressurizer’s pressure control methods is very important. In this paper, an adaptive fuzzy controller is presented for
pressure control of a presurizer in a nuclear power plant. The controller can on-line tune fuzzy control rules and parameters
by self-learning in the actual control process, which possesses the way of thinking like human to make a decision. The simulation
results for a pressurized water reactor plant show that the adaptive fuzzy controller has optimum and intelligent characteristics,
which prove the controller is effective. |
