Abstract

For pressurized water reactors (PWRs), it is traditional method to use proportional-integral-derivative (PID) controllers to adjust the pressure and liquid level of the pressurizer. Traditional PID controllers have limitations, such as fixed parameters and an inability to adapt to changes in operating conditions. To address this issue, this paper proposes an intelligent control method based on a fuzzy neural network (FNN) PID approach for the pressurizer pressure control. To assess the control performance of this proposed method, a simulation code was developed. This code incorporated a two-region non-equilibrium model of the pressurizer, coupling with simulation of PID control, fuzzy PID control, and FNN-PID control. The typical PWRs pressurizer is simulated in the typical variable load transient process. The pressure simulation results under the control of these three controllers are compared, and the effectiveness of the FNN-PID controller proposed in this paper is also verified.
