Firstly the nonlinear model of three-tank water level control system is linearized at a certain operating point, and then a fault detection filter ( FDF) is designed. 首先,对三容水箱系统的非线性数学模型进行线性化处理,并在此基础上设计了基于观测器的故障诊断滤波器。
The linearized filtering results demonstrate the filter with inequality constraints offered a great improvement over the traditional unconstrained filter, particularly for turbofan engine health estimation. 对比传统的无约束卡尔曼滤波,线性化滤波结果显示,该方法对涡扇发动机的健康状况估计尤其行之有效。
