核反应堆功率控制研究

Study on Power Control of Nuclear Reactors

通过对核反应堆进行分析,建立其数学模型,并在此基础上进行PID控制与模糊PID控制,分析了2种控制方式的优缺点.将2种控制策略进行整合,使核反应堆的控制模式可以在2种控制方式下切换.结果表明:将控制策略整合后,核反应堆功率控制的响应时间、超调量和鲁棒性等效果都得到明显的优化提升.

A mathematical model of nuclear reactor was built based on numerical simulation, and subse- quently PID and fuzzy-PID controls were simulated with the model, while advantages and disadvantages of the two control methods were analyzed. By integrating the two control strategies, a compound control mode was proposed for the nuclear reactor, in which case, the control can be switched between the above two methods. Results show that through integration of the two methods, the effects of power control are significantly optimized and improved in the aspects of response time, overshoot and robustness, etc.
