摘要
针对泵压式供应系统液体火箭发动机的健康监控问题,提出了故障检测与诊断的基本框架,并讨论了基于发动机系统非线性数学模型、推广的卡尔曼滤波的故障检测方法和基于低阶线性模型的故障诊断方法。
For monitoring conditions of a liquid rocket engine with turbo-pump system, an outline of fault detection and diagnosis is presented in this paper. The fault detection method with extended Kalman filter based on nonlinear mathematical models and the diagnosis method based on lower-order linear models are also discussed.
