Study on Generalized Predictive Control for the Neutron Flux Density of the Nuclear Reactor

The mathematical model of the neutron dynamic system of the nuclear reactor is transformed into a sort of controlled autoregressive integrated moving average (CARIMA) model. A generalized predictive control method for the neutron flux density is developed. This new control strategy can efficiently eliminate the influence of uncertain perturbations and nonlinearity and can enhance control precision and dynamic qualities of the system. The advantages over the classical control methods are demonstrated by computer simulation.
