Fault Tolerant Control for Steam Generators in Nuclear Power Plant

College of Nuclear Science and Technology, Harbin Engineering University, Harbin, 150001, China

摘要: 基于考虑了随机噪声的蒸汽发生器非线性模型,利用一组扩展卡尔曼滤波器对传感器的状态进行监测,通过实时检测、分离单传感器故障并重构传感器的输出值,达到蒸汽发生器水位稳定的容错控制目的。结果表明,基于扩展卡尔曼滤波器组对蒸汽发生器进行容错控制设计的方法是可行的。

Abstract: Based on the nonlinear system with stochastic noise, a bank of extended Kalman filters is used to estimate the state of sensors. It can real-time detect and isolate the single sensor fault, and reconstruct the sensor output to keep steam generator water level stable. The simulation results show that the methodology of employing a bank of extended Kalman filters for steam generator fault tolerant control design is feasible.
