压水堆负荷跟踪的模糊控制系统

模糊控制理论的发展促进了模糊控制器在压水堆负荷跟踪中的应用。用模糊逻辑控制器和常规ＰＩＤ（比例－积分－微分）控制器相结合，并以输出增闪随功率调整的策略，解决了反应堆负荷跟踪问题，本方法解决了时变非线性对象的闭环控制并克服了基于模型的控制方法的不足，仿真结果显示本文提出的方案不但具有优良的动态特性，而且具有很高的稳态精度，使负荷跟踪控制的自动化程度大为提高。

Fuzzy Logic Control for PWR Load Follow

The developments of fuzzy logic control theory promote the application of fuzzy logic controller to load follow in Pressurized Water Reactors.In this paper,a control law combined fuzzy logic controller with conventional PID controller,using the strategy of output gains varying with nuclear reactor power,was proposed to control load follow operations in PWR.This method solves the nonlinear time varying close loop control problem and overcomes the shortcomings and limitions of the model based method.The simulation results show the method is of both satisfactory dynamic performance and high steady state precision.This approach will improve the automaticity of load follow operations.
