摘　　要：基于考虑随机噪声的蒸汽发生器非线性模型,利用强跟踪滤波器(STF)对蒸汽发生器水位控制系统的传感器故障偏差进行估计,在线诊断故障并重构传感器测量值,实现容错控制。仿真结果表明,该方法可以诊断随机时变的故障偏差,具有很好的容错控制能力。In order to further improve the safety of nuclear power plants,based on the nonlinear system with stochastic noise,the strong tracking filter is used to evaluate the sensor fault bias of steam generator control system and reconstruct the sensors output to implement the fault tolerant control.The simulation re-sults demonstrate that this method can evaluate the time-varying sensor fault bias effectively and has great fault tolerant ability,and the methodology employing the strong tracking filter for steam generator fault tol-erant control design is effective.
