摘　　要：根据动力学原理搭建反应堆堆芯系统集总参数模型,并利用微小摄动理论对该模型进行线性化处理。在此基础上,根据带有回路传输恢复的线性二次型高斯(LQG/LTR)方法设计了堆芯功率控制器。以紧凑型小型堆NuScale堆芯系统为研究对象,将该控制器与传统PID控制器的控制效果进行对比分析。结果表明:利用LQG/LTR方法设计的堆芯功率控制器具有更好的控制指标和抗扰动能力。A lumped-parameter model was established for the core system of a reactor according to the principle of dynamics, which was linearizedly processed using the perturbation theory. On this basis, a core power controller was designed based on LQG/LTR method. Taking the NuScale core system of a compact small modular reactor(SMR) as an object of study, the control effects of this controller and traditional PID controller were comparatively analyzed. Results show that the core power controller designed based on LQG/LTR method has better control effect and higher anti-disturbance capability.
