Abstract:
A system and method for controlling an electrically controlled pressure relief valve may use a soft position control loop to control the position of the valve. A pressure relief valve may also include a modified orifice shape to improve stability, to uniformly distribute the effective bandwidth over the valve operating range, and to provide a tunable default mode.
