运用模糊控制理论，针对稳压器压力控制的特点，为解决核动力装置折中稳态运行方案下低工况运行时一回路压力随负荷变化波动较大的问题，设计了压力模糊控制器。即利用模糊控制器实现稳压器压力调节系统工作参数的在线优化自整定，并以某核动力装置为对象进行了仿真实验。仿真结果表明，本控制器在对原系统不作大改动的前提下，能有效地抑制一回路压力波动，比原有调节系统具有好得多的调节品质。
According to the characteristics of the pressure control of the pressure regulator, a fuzzy controller is designed to solve the problem that the pressure of the primary circuit fluctuates greatly with the change of load under the condition of medium operating steady-state under the compromise of steady-state operation of the nuclear power plant. That is, the fuzzy controller is used to realize the online self-tuning of the working parameters of the pressure regulating system of the regulator. The simulation experiment is carried out with a nuclear power plant as an object. The simulation results show that under the premise that the controller will not make major changes to the original system, it can effectively restrain the pressure fluctuation of the primary loop and has much better regulation quality than the original one.
