Abstract
In a method of controlling a hydraulic actuator of a test station, a differential signal is generated based on a difference between a reference signal and a feedback signal using an actuator controller. A flow rate control circuit is set in one of a first state and a second state based on a flow rate attenuation signal. The differential signal is delivered to the control valve as an actuator command signal when the flow rate control circuit is in the first state. An attenuated differential signal is delivered to the control valve as the actuator command signal when the flow rate control circuit is in the second state. A flow rate and a direction of the hydraulic fluid flow is controlled based on the actuator command signal. The flow rate corresponding to the attenuated differential signal is less than the flow rate corresponding to the differential signal.
