Abstract
Controlling fluid regulation may provide increased efficiency and reliability. In one general aspect, a system and process for fluid regulation may include the ability to receive a command signal, generate a control signal based on the command signal, and move a magnetizable element relative to a wire coil in accordance with the control signal, the movement affecting a pressure in a pressure cavity. The system and process may also include the ability to sense the pressure in the pressure cavity due to the position of the magnetizable element and adjust the control signal based on the sensed pressure and the command signal. The system and process may further include the ability to sense a second parameter of the fluid regulation system and adjust the command signal based on the second parameter.
