The Preliminary Research of Pressure Control System Danymic Simulation for AplOOO Pressurizer Based on Parameter Adaptive Fuzzy Pid Control Algorithm

摘要

According to the characteristics of AP1000 pressurizer dynamic process, using AP1000 nuclear plant parameters, a model of pressurizer pressure control system for nuclear power plant is established in this paper. Simulation experiments have been performed using acslX software according to AP1000 pressurizer pressure control system design. Parameter adaptive fuzzy PID controllers have been designed to improve the control function based on the original PID controllers. The comparison between the simulating results indicates that the improved controllers give better performance than the original ones and has a reference value for further control strategies optimization of the pressurizer pressure control system.
