Fault detection in a system under control |
摘要 |
A method (300) for fault detection in a system under control includes monitoring a command value and a wraparound signal (301) by a fault detection module (203); determining a standard deviation of the command value (302) by the fault detection module; determining a standard deviation of the wraparound signal (303) by the fault detection module; determining a ratio of the standard deviation of the command value to the standard deviation of the wraparound signal (304) by the fault detection module; and determining the presence or absence of a fault in the system under control by the fault detection module based on the ratio (305) by the fault detection module. A fault detection module (203) and a computer program product comprising a computer readable storage medium containing computer code that, when executed by a computer, implements a method (300) for fault detection are also provided. |
