Abstract

Abstract

Lead-bismuth cooled fast reactors are mostly used for isolated power supply in remote and special environments such as oceans and mountains. The characteristics of users require that small lead-bismuth cooled fast reactors have good load following ability. In this paper, three different control methods are applied to the core power control of lead-bismuth cooled fast reactor, and the stability and set value tracking ability of the controller are tested by introducing noise, dead zone and time lag. The results show that the proportional integral derivative (PID) controller is difficult to achieve good control effect, so other links are often added in industrial applications to ensure the stability of the PID controller. Both active disturbance rejection control (ADRC) and H_∞ robust controller have good anti-noise ability, and can independently achieve good control effect, but good anti-noise ability must sacrifice a certain sensitivity. The comparative analysis of the three kinds of controllers shows that because the simulation calculation simplifies the actual object, the controller designed under such conditions shall be designed with more conservative parameters.
