Core power control of the ADS based on genetic algorithm tuning PID controller

Abstract

The accelerator driven subcritical system (ADS) reactor, an accelerator driven transmutation research facility relies on control rod and external neutron source to realize core power regulation. This paper researches the dynamic and control characteristics of the ADS core under the external neutron source disturbance. The state space model of the ADS core with multi-input multi-output is established by linearizing the core nonlinear model with small disturbance. The response characteristics of the ADS core power control under external neutron source strength regulation are simulated by using genetic algorithm tuning proportional-integral-derivative (PID) controller and traditional PID controller. The results show that under different external neutron source relative strength, the effect of genetic algorithm tuning PID controller is better than that of traditional PID controller. The ADS core power can be well controlled by using genetic algorithm tuning PID controller.
