A predictive control method of the neutron flux density for a nuclear reactor

In this paper, a kind of non-parameter model is constructed with the unit step response of the nuclear reactor neutron dynamic system. Furthermore, a kind of constant neutron flux density control law is presented using a predictive control algorithm. In contrast to the other control methods based on the accurate model, the method presented in the paper has better tracking performance and robustness. It can work despite the existence of unmeasurable disturbances. Simulation experiments are done through comparing with state feedback control, the results testify the correctness and effectiveness of the predictive control method.
