Research on Core Power Control of Small Lead-based Reactor Based on Ant Colony Algorithm

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. © 2022, Editorial Board of Journal of Nuclear Power Engineering.
