核电站反应堆中子注量率的预测控制仿真研究

Simulation Study of the Neutron Flux Predictive Control 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,获得了该系统的非参数模型,且提出了一种中子注量率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,此方法不必苛求模型的具体形式,且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。仿真结果验证了这种控制律的有效性和优越性。

A sort of non-parameter model is constructed with the unit step response of the nuclear reactor neutron kinetics system. Furthermore, a sort 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 this paper has good tracking performance and robustness. It can work despite the existence of un-measurable disturbances. The simulation experiment testifies the correctness and effectiveness of the method.
