核电站反应堆中子通量密度的一种预测控制方法

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

利用核电站反应堆中子动力学系统的单位阶跃响应数据，得到了该系统的非参数模型。提出了一种中子通量密度恒值问题的预测控制方法、与基于精确模型的控制方法相比，该方法不必苛求模型的具体形式，实时控制的计算量小、跟踪调节性能好、鲁棒性强、能消除不可测干扰。通过与状态反馈控制方法的仿真比较，验证了这种控制律的有效性和优越性。

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.
