基于平方根容积卡尔曼滤波的核反应堆功率H∞控制
Discrete H∞ control of nuclear reactor power based on Square-root Cubature Kalman Filter
摘要
Abstract
The nuclear reactor's load-following control was one of the foundations for nuclear power plants'flexible peak-adapting,and also one of the reasons of nuclear power plants's application value.In this paper,the Square-root Cubature Kalman Filter(SCKF)of the nuclear reactor,which had solved the problem that some of the nuclear reactor's state variables can not be measured or estimated accurately,was constructed based on mathematical models such as reactor neutron dynamics equation,thermo-hydraulics equation,and reactivity equation,and the reactor power H∞controller based on SCKF was designed by combining the discrete H∞ performance index,and compared with the reactor power H∞ controller based on the classical Kalman Filter(KF)through numerical simulationunder the same operating conditions simultaneously.The simulation results showed that the power controller based on SCKF had good load-following performance,and the controller based on SCKF was able to regulate the reactor power level according to the expected targets;due to the higher state estimation accuracy of SCKF compared with KF in nonlinear system models,the power controller based on SCKF had the better control performance compared with the controller based on KF.关键词
