Abstract
An impending fault of a component operated within a closed-loop control system can be detected. The close-loop control system is disabled. An actuator of the closed-loop control system is operated at one or more test values. A sensor reading of the actuator is taken while that actuator is operated at the one or more test values. A warning is generated if an impending fault condition is detected. An impending fault condition may be detected if the component operates at a value exceeding a maximum defined operating value, if the component operates at a value below a minimum defined operating value, or if an operating range that is narrower than a defined full operating range for the component is detected.
