Abstract
A system and methods for non-optimal actuator detection are disclosed. A fluid valve controlling a fluid flow to a first actuator is activated, and the fluid valve is controlled to move the first actuator from an initial position to a first position and back to the initial position during a test interval. A measured valve position of the fluid valve is measured during the test interval, and a measured valve travel is calculated based on the measured valve position at an end of the test interval. A health status of the first actuator is determined based on the measured valve travel and an expected valve travel.
