Approach for monitoring energy consumption and preventive maintenance of a system based on control loop efficiency

摘要

An approach for monitoring energy consumption and detecting preventive maintenance issues in a system having control loops and associated devices. Settling time and error value in a control loop may be indicative of the loop's efficiency. Error value may be a difference between a measurement of a parameter and a setpoint for the parameter. Degradation of a loop's efficiency may be an indication of increased energy consumption by the system. Such degradation may also be indicative of a future defect in a control loop or devices associated with the control loop. Thus, the present approach may provide for energy monitoring and preventive maintenance of the system.
