Data model-based sensor fault diagnosis algorithm for closed-loop control systems

•A linear model is dynamically established based on the gradient change of the control variables from the sensor data, and a baseline model tracker is designed.•The engine baseline model is trained and updated using historical data from healthy sensors.•Reasonable diagnostic thresholds are calculate...
