Abstract: Systems, methods, and computer-readable media for fault detection are disclosed. At least one controller may identify a plurality of values where each value corresponds to a monitored parameter or a measured parameter. The at least one controller may determine a respective deviation between each of the plurality of values and an expected value, and may further determine whether at least one of the respective deviations exceeds a threshold. Upon a determination that at least one of the respective deviations exceeds the threshold, a fault may be detected. Each of the plurality of values may be associated with a respective device that monitors or measures the value. A detected fault may be associated with the device that monitors or measures the value determined to deviate from the expected value by more than the threshold.
