Abstract: A computer-implemented method for determining a scheduled maintenance session for a proportional actuator includes transmitting a command signal to a controller of the proportional actuator and generating, using the controller, a drive signal for controlling the proportional actuator using the command signal. The position of a component actuator of the proportional actuator is changed, on the basis of the drive signal, and the position of the component actuator is measured, using a sensor, and a position feedback signal is generated on the basis of the measurement. A condition indicator is estimated, with a processor, using only one of the command signal, the drive signal, or the position feedback signal. A health indicator is estimated, with the processor, using the condition indicator, and a scheduled maintenance session of the proportional actuator is determined, with the processor, using the health indicator.
