Abstract

A solenoid operated valve is controlled upon increasing energization for greater flow by incrementing by a small fraction of the maximum current a target current level for the desired flow for a short duration followed by energization at the target level. Upon decreasing energization for lesser flow, the valve is energized at a target current decremented by a small fraction of the maximum current for a short duration. The result is a nearly negligible hysteresis.
