【Abstract】 Good sensor is the base of the testing, monitor, control and the diagnostic technology. So, the sensor status recognization technique is the one of the most task for fault diagnosis. This paper brings forward and discusses the dynamic diagnostic algorithm based on the analytic redundancy observer. And this algorithm may be used in the locomotive sensor on line diagnosis system.更多还原
