摘要: 为提高核电厂稳压器压力的控制性能,针对其升、降压不同的被控特性,结合可以实时调整控制器参数的模糊自适应比例、积分、微分(PID)控制,设计出基于2个模糊控制器的压力控制系统。通过MATLAB/simulink仿真表明,采用模糊控制器的稳压器压力控制系统使控制性能得到了明显的改善。Abstract: To improve the control performance of pressurizer pressure in PWRs, according to different controlled characteristics of pressure rising and reducing, the fuzzy adaptive PID control which can timely adjust parameter of controllers is considered, and the pressure control system using two fuzzy controllers is designed. Simulation on MATLAB/simulink demonstrates that the control performance of this pressurizer pressure control system using fuzzy controllers is obviously improved.
