Abstract:
A plant includes equipment that operate to affect a variable state or condition of the plant in response to a control signal. A feedback controller monitors a process variable received via a feedback signal from the plant and uses an error signal representing a setpoint error between the process variable and a setpoint to generate the control signal for the plant. An exponentially-weighted moving average (EWMA) calculator generates EWMA values based on the setpoint error. A normalized index generator uses the EWMA values to calculate a normalized performance index. A threshold generator generates a threshold based on a first alarm parameter κ representing a normalized magnitude of the setpoint error and a second alarm parameter η representing a normalized duration that the setpoint error has persisted. An alarm manager generates an alarm in response to the normalized performance index crossing the threshold.

Claim (Index 3):
The feedback control system of  claim 1 , wherein the threshold represents an expected value of the normalized performance index when the setpoint error exceeds a predetermined magnitude and has persisted for a predetermined duration.
