Abstract
A monitoring system includes a processor configured to calculate a first distance of a first signal, wherein the first distance represents changes in magnitude of the first signal over a period of time, and wherein the first signal is associated with a desired signal output of a feedback loop system. The processor is configured to receive a second signal from an output of the feedback loop system. The processor is configured to calculate a second distance of the second signal, wherein the second distance represents changes in magnitude of the second signal over the period of time. The processor is configured to determine a first difference between the first distance and the second distance. The processor is configured to provide an error signal indicating an error if the difference exceeds a threshold value.
