Method to quantify closed loop position control health
First Claim
1. A monitoring system, comprising:
- a processor configured to;
calculate a first travel distance of a first signal, wherein the first travel distance corresponds to a first linear distance representative 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;
receive a second signal from an output of the feedback loop system;
calculate a second travel distance of the second signal, wherein the second travel distance corresponds to a second linear distance representative of the second signal over the period of time;
determine a first difference between the first travel distance and the second travel distance; and
provide an error signal indicating an error in response to the first difference exceeding a threshold value, wherein the error signal causes one or more actuators to adjust one or more positions of one or more vanes associated with an engine.

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.
