Abstract
In one aspect, a system for rephasing fluid-driven actuators includes a plurality of fluid-driven actuators fluidly coupled together in series. A controller is configured to monitor a position differential existing between current positions of rods of the actuators relative to a differential threshold based on sensor measurements. The actuators are out-of-phase when the monitored differential exceeds the threshold. The controller is also configured to initiate a flow of fluid to the actuators to rephase the actuators when the monitored differential exceeds the threshold. The controller is further be configured to continue to monitor the differential following initiation of the flow of fluid to the actuators. Additionally, the controller is configured to implement a control action associated with terminating the rephasing of the actuators when the monitored differential remains constant after a first time period has elapsed following initiation of the flow of fluid.
