摘　　要：小型铅基堆适用范围广、运行工况复杂多变,采用传统的控制方法难以实现堆芯功率的良好控制。为解决传统线性二次高斯控制(LQG)/回路传输恢复技术(LTR)控制器参数无法实现在线调整问题,采用微扰理论建立堆芯状态空间模型,设计一种基于蚁群算法的LQG/LTR控制器,建立小型铅基堆堆芯功率控制系统,实现了LQG/LTR控制器参数在线调整,并开展了堆芯动态仿真研究。结果表明,基于蚁群算法的LQG/LTR控制器相较于传统LQG/LTR控制器更易达到稳定,且变化幅值更小。Small lead-based reactor has a wide range of applications and complex and changeable operating conditions.It is difficult to achieve good control of core power by using traditional control methods.In order to solve the problem that the parameters of the traditional linear quadratic Gaussian control(LQG)/loop transmission recovery technology(LTR)controller cannot be adjusted online,the core state space model is established by using the perturbation theory,an LQG/LTR controller based on ant colony algorithm is designed,the core power control system of small lead-based reactor is established,the parameters of LQG/LTR controller are adjusted online,and the dynamic simulation of the core is carried out.The results show that the LQG/LTR controller based on ant colony algorithm is easier to be stable and the amplitude of change is smaller than that of the traditional LQG/LTR controller.
