    • The disclosure provides a method, system and internal combustion engine system in which a closed-loop system having a controllable variable is monitored to detect the off- nominal behavior of the closed-loop system and raise an alarm or other alerting mechanism when fault is detected. The faults in a closed-loop system show up in such a way that the tracking error signal is impacted and this impact manifests itself as a change in the frequency components. A filter is used to isolate a band of frequency components of the tracking error signal that are more impacted than other by deviation caused by a fault to be detected. The filter can be designed to effectively amplify the section of the error tracking signal that contains the frequency components that have the major impact. In addition, the filter will also have the characteristics to attenuate the impact of other frequency components. An accumulated error signal is generated from the filtered tracking error signal, compared with a predetermined fault threshold characteristic, and a fault indication/warning/alert is provided for the closed- loop system if the accumulated error signal meets the predetermined threshold.
    • 本公开提供了一种方法,系统和内燃机系统,其中监控具有可控变量的闭环系统以检测闭环系统的非标称行为,并且在检测到故障时提高报警或其他报警机制 。 闭环系统中的故障显示为跟踪误差信号受到影响,并且这种影响本身就表现为频率分量的变化。 使用滤波器来隔离跟踪误差信号的频带的频带,其比通过由待检测的故障引起的偏差更多地受到影响。 滤波器可以被设计成有效地放大包含具有主要影响的频率分量的误差跟踪信号的部分。 此外,滤波器还将具有衰减其他频率分量的影响的特性。 与预定的故障阈值特性相比,从滤波的跟踪误差信号产生累积的误差信号,并且如果累积误差信号满足预定阈值,则为闭环系统提供故障指示/警告/警报。
